Reference no: EM13682503

A train traveling at v0 = 20.0 m/s begins to brake by applying a velocity-dependent instantaneous acceleration a(v) = ? /(v u) m/s2, where ? = – 24.0 m2/s3, v is the instantaneous velocity of the train, and u = 0.5 m/s. Decide the distance traveled by the train until it comes to a complete stop.
