a 40 x 10^3 kg train is travelling at 8.3m/s when the engineer sees a sheep on the tracks. she throws the emergenxy brakes on. the emergency brakes can apply a maximum force of 11x10^3 N.
a. How long is it before the rain will come to a complete stop?
b. the sheep startled by the sparks and noise of the emergency brakes trots off the tracks. the engineer is able to release the brakes. if the brakes had been applied for 11s how fast is the rain travelling now?
