A ball of mass 150 g starts moving with ...

A ball of mass 150 g starts moving with an acceleration of `20m//s^(2)`. When hit by a force, which acts on it for `0.1` sec. The impulsive force is

A

`0.5 N-s`

B

`0.1 N-s`

C

`0.3 N-s`

D

`1.2 N-s`

Text Solution

Verified by Experts

The correct Answer is:
C
Impulse = force `xx` time = m a t
` = 0.15 xx 20 xx 0.1 = 0.3 ` N sec.
