A 70-kg base runner begins his slide into second base when he is moving at a speed of 4.0 m/s. The coeffi-cient of friction between his clothes and Earth is 0.70. He slides so that his speed is zero just as he reaches the base.
(a) How much mechanical energy is lost due to friction acting on the runner?
(b) How far does he slide?
In the situation below, m1=20 kg and m2=10 kg. The masses are at rest.
A) What is the minimum coefficient of friction between the incline and m1?
B) The sting and cut and m1 slides down the incline. What is its speed when it reaches the bottom? The block is initially at height of 10 meters.
