Different masses change the temperature at different rates when they are exposed to the same amount of thermal energy. The reason for this is that the amount of mass affects an object's ability to absorb thermal energy.
Thermal energy is the energy enclosed within a system that controls its temperature. Heat is also defined as the flow of thermal energy. Thermodynamics is a branch of physics that deals with how heat is transmitted between various systems and how work occurs in the process.
Once the temperatures are equal, there is no net heat transfer because the amount of heat transmitted from one object to the other is equal to the amount of heat returned. Temperature change is a significant effect of heat transfer: Heating raises the temperature, while cooling lowers it.

A red cart ma = 2kg and a blue cart ma = 2 kg are ELASTICALLY crahed into each other at the indicated velocitie and bounce. After the colliion which cart will have the SMALLEST peed
The objects in an elastic collision split apart after impact while maintaining all of their kinetic energy. Kinetic energy, often known as the energy of motion, is discussed in more detail elsewhere.
How do you find the velocity of a bounce?When the ball is not in contact with the ground, the formula h(t+t0)=v0t12gt2 determines the height at time t following the previous bounce at time t0. where v0 denotes the speed shortly before the bounce.
The mass of the red cart, m1, is equal to m1u1 + m2u2 = m1v1 + m2v2.
The blue cart has a mass of m2.
The red cart's starting speed is u1.
The blue cart's starting speed is u2.
The red cart's ultimate speed is v1.
The blue cart's ultimate speed is v2.
The final speed of each cart is determined by the formula: v1 = [m1u1 + m2u2 - m2v2] / m1
m1u1 + m2u2 - m1v1 = v2 / m2
As m1 = m2, our new equation is: v1 = u1 + u2 - v2.

How do you find the magnitude and direction of displacement?.
Calculate the inverse tangent of the ratio of the displacement components in the y and x directions to determine the direction of the displacement vector. The magnitude of displacement is equal to the distance covered in a given interval of time if the particle moves at a constant or variable velocity in the same direction, because if it changes direction, the magnitude of displacement changes and does not remain equal to the distance covered.
A quantity with magnitude and direction must also follow certain combination rules in order to qualify as a vector. Vector addition, denoted symbolically as A + B = C, is one of these (vectors are conventionally written as boldface letters). Geometrically, the vector sum can be visualized by placing the tail of vector B at the head of vector A and drawing vector C so that it completes the triangle (starting from the tail of A and ending at the head of B). If A, B, and C are vectors, then it must be possible to reverse the operation and achieve the same result (C), B + A = C. This property (commutative law) is shared by quantities such as displacement and velocity, but there are some that do not (for example, finite rotations in a circle).

If a ball i thrown horizontally from the roof of a building 55 m tall with a speed of 3. 8 m/ so the ball will land 55 m away from the building.
What is speed?Speed is the rate at which something moves or occurs. It is usually measured in terms of distance over time. Speed can be expressed in many different forms, including miles per hour (mph), kilometers per hour (kph), meters per second (m/s) and even in terms of the speed of light. Speed is a measure of how quickly something moves in a specific direction.
The ball will land 55 m away from the building. This is because the horizontal velocity of the ball is 3.8 m/s, and the time it takes to travel 55 m is 55/3.8 = 14.47 seconds. Since the ball was thrown horizontally, it will travel a horizontal distance equal to the time it took multiplied by the velocity, which is 14.47 * 3.8 = 55 m.

What is distance?Distance is a measurement of how far away two things or locations are, either numerically or occasionally qualitatively. Distance can refer to a physical length in physics or to an estimate based on other factors in common use.Distance is the sum of an object's movements, regardless of direction. Distance may be defined as the amount of space an item has covered, regardless of its beginning or finishing position.A span is any distance between two objects. These end points may be concrete, like the length of a rope between two trees, or they could be more ambiguous, like the interval between five and six o'clock in the morning.Given data :
Let’s review the 4 basic kinematic equations of motion for constant acceleration (suggest you commit these to memory):
s = ut + ½at^2 …. (1)
v^2 = u^2 + 2as …. (2)
v = u + at …. (3)
s = (u + v)t/2 …. (4)
where s is distance, u is initial velocity, v is final velocity, a is acceleration and t is time.
First, we find the time taken by the projectile to drop 84m. From equation (1):
84 = 0 + 0.5(9.81)(t^2) so t = √(84/4.905) = 4.14s
Next, we find the distance travelled in 4.14s at 10m/s, which is:
Distance = 4.14*10 = 41.4m

If you add 20g of ice at 0 degree celciu to 180g of water at 20 degree celciu, what i the final temperature of the water a all of the ice melt?
The combined water and melted ice temperature is 31.15°C.
We can use the following formula:
q = m c T is used to calculate the final temperature of the water and melted ice, where:
q = added or lost heat
m = the substance's mass
c = the substance's specific heat capacity
T = temperature change
Finding the heat that the ice has taken away:
(20g) x (2.1 J/g°C) x (0 - (-20))°C = q
q = 8400 J
Identifying the heat gained by water:
(180g) x (4.18 J/g°C) x (T) = q
Taking the heat lost by ice and converting it to the heat gained by water
(180g) x (4.18 J/g°C) x (T) = 8400 J
Trying to find T
T = 8400 J/(180g x 4.18 J/g°C).
ΔT = (8400/756)°C = 11.15°C
We get the final temperature by adding the initial temperature of the water to the temperature change.
T(f) = 20°C + 11.15°C = 31.15°C

What is kinetic energy?Kinetic energy is the energy possessed by an object or a particle due to its motion. It is the energy of motion and can take many forms, such as the energy associated with an airplane flying through the air, a ball rolling down a hill, a person running, or a car traveling on a highway. In general, kinetic energy is the energy an object has because of its movement.
The kinetic energies of the two bullets can be calculated using the equation KE = (1/2)mv2, where m is the mass of the object and v is the velocity of the object.
For the first bullet, KE = (1/2)(3.0 g)(40.0 m/s)2 = 480 J.
For the second bullet, KE = (1/2)(3.0 g)(80.0 m/s)2 = 1920 J.
