Introduction: Physics

More Details: (a) A light-rail commuter train accelerates at a rate of 1.35 m/s2. How long does it take it to reach its top speed of 80.0 km/h starting from rest?

s

(b) The same train ordinarily decelerates at a rate of 1.95 m/s2. How long does it take to come to a stop from its top speed?

s

(c) In emergencies the train can decelerate more rapidly, coming to rest from 80.0 km/h in 8.30 s. What is its emergency deceleration in m/s2?
