Thermal Properties of Materials

In mechanical engineering, the thermal property is represented as the physical quantity that is relevant to the application of heat. The thermal properties are evaluated by variations in any specific material due to low heat or high heat. The quantities that influence the thermal property of the materials are mass, density, temperature, and many others.

Question

Q11. As shown in the image below, the freight cars A and Bare approaching each
other, and they have a mass of mA = 19 Mg and mB = 14 Mg, respectively. The
directions of their initial velocities are shown in the image, and the speeds are vA,1 =
9.2 m/s and vB.1 = 6.8 m/s. If the coefficient of restitution between the bumpers is e
= 0.4, determine the velocity of A after collision. Right is considered the positive
direction and negative sign must be included if A moves to the left after the collision.
Please pay attention: the numbers may change since they are randomized. Your
answer must include 3 places after the decimal point, and proper SI unit.
