A small ball of mass `m=1` g is placed at the bottom of a watch glass of radius `R=1` m. It is displaced by `h=1` cm along the glass surface and released. Calculate the total distance deseribed by it before it comes to rest at the bottom, if `mu =0.1` is the coefficient of friction between the ball and the watch glass.

A small head of m is pleced in the bottom of which glass of value radius R It is displaced by (h ltlt R) along the glass surface and released calculate the total distance described by it before it comes to rst of the botom mu is the coefficient of friction between bead and the watch glass

A ball is dropped from a height of 3m . If coefficient of restitution between the surface and ball is 0.5 , then the total distance covered by the before it comes to rest is

Find the mass M in the situation shown in figure-2.212 such that m remains at rest on the front surface of M_(1) . The coefficient of friction between the front surface of M_(1) and that of m is mu .

A body of mass m moves with a velocity v on a surface whose friction coefficient is mu . If the body covers a distance s, before it comes to rest, then v will be :

A simple pendulum of length l and consisting of a ball of mass m is released from a position making an angle theta=cos^(-1) (0.8) with the vertical and strikes at its lowest position a block of mass M resting on a rough horizontal plane. If the coefficient of kinetic friction between the plane and the block is 0.2 find (a) How long the block will move along the plane, if the ball of the pendulum rebounds to an angle beta=cos^(-1) (0.9)A (b) The coefficient of restitution, use (M)/(m) =10 and 1= 1 m
