A small 080-kg train propelled by a fan engine starts at, Ask an Expert

Academics

A small 0.80-kg train propelled by a fan engine starts at rest and goes around a circular track with a 0.80-m radius. The fan air exerts a 2.0-N force on the train. Ignore the force friction.

Part A. Determine the rotational acceleration of the train.

Part B. Determine the time interval needed for the train to acquire a speed of 3.0 m/s.
