Question

10
Ans. 600 ms
A body moving with a constant acceleration
travels the distances 3 m and 8 m respectively in 1
s and 2 s. Calculate : (i) the initial velocity, and (ii)
the acceleration of body.
Ans ( 2 -1 (il 2 m -2
​

Answer 1

Initial velocity,u=3/1 m/s

=3m/s.

Final velocity,v=8/2 m/s

=4m/s.

Acceleration of body=change in velocity/time

= 4-3/2

=0.5m/s^2.
