1. The problem statement, all variables and given/known data
a toy train rolls around a horizontal 1.0m diameter track. the coeffifient of rolling friction is 0.10
a. what is the magnitude of the train's angular acceleration after it is released
b. how long does it take the train to stop if it's released with an angular speed of 30rpm.
