Question

A particle starts from rest and moves with uniform acceleration of 5m/s^2 for 10s and then it moves with constant velocity for 4s. Later it slows down and come to rest in 5s . Draw the velocity graph for the motion motion of the body and the following questions:
A. what is the maximum velocity attended by the body ?
B. what is the distance travelled during this period of acceleration?
C. What is distance travelled when the body was moving with constant velocity?
D. what is the retardation of the body while slowing dowm ?
E. What is the distance travelled by regarding?
F. what is the total distance travelled?​

Answer 1

=20m/s

For region III,t=

4

20

=5sec

Distance covered is equal the area under velocity time graph
