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

A

0.1N

B

0.5N

C

0.3N

D

1.2N

Text Solution

Verified by Experts

The correct Answer is:
C
Force = mass `xx` acceleration
and Impulse `(J)= Fxxt= mxxa xx t`
`therefore J= 150xx10^(-3) xx 20 xx 0.1=300 xx 10^(-3)= 0.3N`
