Question

1. A train starts from rest and accelerates uniformly at the rate of 2ms-2 until it attains a maximum velocity in 20s. It maintains this velocity for 60s and then retards uniformly to rest after a further 20s. Draw a graph of the motion and use the graph to determine:

a. Maximum velocity reached

b. Retardation

c. Distance covered

Answer 1

Answer:

it will reach maximum speed .As time is going on increase body is acceleerarting and retardation.
