Q1. A toy train rolls around a horizontal 1.2--diameter track. The coefficient of rolling friction is 0.15.

What is the magnitude of the train's angular acceleration after it is released? (Found)

How long does it take the train to stop if it's released with an angular speed of 33rpm?

Q2. If a car travelling at 52 km/h will skid 18 m when its brakes lock, how far-off will it skid if it is travelling at 120 km/h when its brakes lock?
