Question

A train starts from rest and accelerates uniformly at a rate of 2 ms^-2 for 10s. It then maintains a constant speed for 200s . The brakes r then applied and the train is uniformly retarded and comes to rest in 50s. Find maximum velocity reached ( in m/s)?



plz help me​

Answer 1

Answer:

20m/s

I'm not sure about the answer. I think only first half of the question is important. After that it maintains a constant speed and decelerates.
