Two identical smooth spheres, each of mass 0.40kg, collide on a frictionless horizontal surface. Sphere P moves with speed 3.0ms−1 towards stationary sphere Q in a head-on collision.
a. (i) Find the loss of kinetic energy if the coefficient of restitution is 0.
b. (ii) Find the loss of kinetic energy if the coefficient of restitution is 0.6.
c. (iii) Determine the ratio ΔKe=0ΔKe=0.6.
