Two objects with masses 2.0 and 3.0 kg move toward each other, both with speeds V0 = 5.0 m/s. They collide head on and stick together.

Question

(a) Calculate their final velocity.
(b) Calculate the amount of kinetic energy lost during the process.
(c) Suppose the two masses approach each other at 90° before the collision (e.g., along the x- and y-axes). What will be the kinetic energy loss in this case?

Answer 1

Calculate the angle of minimum deviation for a ray which is refracted through an equiangular prism of refractive index 1.4
