Question

The velocity of a body increases from 10m/s to 25m/s covering a 60m distance. Find out the time required to travel this distance and the acceleration obtained by the body.

Answer 1

Explanation:

Correct option is

B

4 m/sec

v

i

=10 m/s and v

f

=20 m/s

Acceleration of the body =

5

20−10

m/s

2

a=2 m/s

2

Velocity of the body at t=−3 sec

v=u+at

v=10−2×3

v=4 m/s
