Answer #1

Given the initial velocity of the stone u = 4.3m/s and the coefficient of friction between the stone and the ice is = 0.05. Since the stone eventually comes rest, the final velocity v = 0m/s. Let L be the distance travelled by the stone before coming to rest, then

On a surface with friction, the force acting on the stone is

Therefore,

So the stone travels 18.87m before coming to rest.

A solid, spherical ball slides with speed 4.48 m/s across frictionless ice and then encounters a rough patch with a coefficient of kinetic friction µk = 0.198. The ball is initially not rotating but the friction causes it to start spinning. How far does it slide across the rough spot before it begins to roll without slipping? Express your answer in metres.
