If a train going 60 m/s hits the brakes and it takes the train 1 minute and 40 seconds to come to a complete stop, what is the train's acceleration?

The rocket is fired vertically and tracked by the radar station shown. when θ reaches 66°, other corresponding measurements give the values r = 32700 ft, r¨ = 85 ft/sec2, and θ˙ = 0.019 rad/sec. calculate the magnitudes of the velocity and acceleration of the rocket at this position.
