Question

A car starts from rest and accelerate uniformly at the rate of 2ms-2 for 20 second. It then maintains a constant velocity for 10 second. The brakes are then applied and the car is uniformly retarded and comes to rest in 5 second. Draw the v-t graph for the motion and find (a) the maximum velocity (b) the retardation in last 5s and (c) total distance travelled.

Answer 1

Answer:

A Train Starts from Rest and Accelerates Uniformly at a Rate of 2 M S-2 for 10 S. It Then Maintains a Constant Speed for 200 S. the Brakes Are Then Applied and the Train is Uniformly Retar Concept: Acceleration and Retardation.
