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 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 skier slides horizontally along the snow for a distance of 21 m before coming to rest. The coefficient of kinetic friction between the stier and the snow is mu_(k)=0.050 . Initially, how fast was the skier going ?

A parallel beam falls on solid glass sphere of radius R and refractive index mu . What is the distance of final image after refractioin from two surfaces of sphere? What is the condition for the image to be real?

A block of mass m is pushed momentarily along a horizontal surface with an initial velocity u. If mu_k is the coefficient of kinetic friction between the object and surface, find the time at which the block comes to rest.
