Question

Q3. A body starts from rest and moves with a uniform acceleration of 5m/s² for 5s and then it moves
with a constant velocity for 4s. Later it slows down and comes to rest in 5s. Draw the velocity
time graph for the motion of the body and answer the following questions:
a) What is the maximum velocity attained 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 down?
e) What is the distance travelled by retarding?
f) What is the total distance travelled?​

Answer 1

Answer:

A- 25m/s

b- d- 25 m

c- d- 100m

d- a - 20m/s^-2
