Question

A motorcycle is traveling at 20 m/s when it enters the test section of a circular track with a 1000-m radius. Once in the test section, the cycle slows down and its deceleration along the track varies with its position, s, by the relation a(subscript t) = -2.10s^2 (m/s^2). Determine
1.) The distance traveled within the test section until it comes to a stop.
2.) The magnitude of its acceleration at s = 5 m.
