A rolling cart carrying books has a mass of 30 kg and is shoved so that it is given an initial velocity of 3 m/s. The cart's bearings are such that the coefficient of friction can be treated as 0.2 and friction acts to slow the cart to rest. a) What is the magnitude of the cart's acceleration as friction acts upon it?
b) How much time does it take for the cart to come to rest?
c) How far does the cart roll before it comes to rest?
