A disc of mass `M` and radius `R` is rolling purely with centre's velcity `v_(0)` on a flat horizontal floor when it hits a step in the floor of height `R//4` The corner of the step is sufficiently rough to prevent any slippoing of the disc against itself. What is the velocity of the centre of the disc just after impact?

A uniform disc of mass m and radius R is projected horizontally with velocity v_(0) on a rough horizontal floor so that it starts with a purely sliding motion at t= 0. After t_(0) seconds it acquires a purely rolling motion. (a) Calculate the velocity of the centre of mass of the disc at t_(0) (b) Assuming the coefficient of friction to be mu , calculate to. Also calculate the work done by the frictional force as a function of time and the total work done by it over a time t muchlonger than t_(0) .
