question mark

A solid sphere is rolling without slipping (w,v) on rough ground. It collides elastically with an another identical sphere at rest ther is no friction b/w the spheres. radius of each sphere is R and mass m.What is the net angular impulse imparted to the second sphere during collision

i think the ans is zero because due to elastic collision only linear velocity of 1^st sphere is changed to zero but as there is no friction between the spheres the angular velocity of 1^st sphere remains the same and the 2^nd sphere only follows translational motion

the answer is not zero. There is no friction b/w the spheres but the ground is rough due to this there exists certain angular impulse

An object of mass m = 0.25 kg oscillates in a fluid at the end of a vertical spring of springconstant kH = 85 N/m, see Fig.1. The effect of the fluid resistance is governed by thedamping constant b = 0.07kg/s.(i) Find the period of the damped oscillation.(ii) By what percentage does the amplitude of the oscillation decrease in each cycle?
