A light commuter rail train usually accelerates at a rate of 2.15 m/s^2 and usually decelerates with a rate of 3.20 m/s^2 (given as magnitudes) The train can reach a maximum speed of 90 km/hr.

a) how much time does it take to reach its top speed starting from rest?

b) how much time doe sit take to come to a complete stop from its top speed?

c) The train can stop in 10.5 seconds from its top speed in an emergency. How far would it travel during this braking period?
