Question

13.A cricket ball of mass 0.20 kg is moving, with a ant force for 10 seconds the velocity o of 1.2m/s.
Find the impulse on the ball.

Answer 1

Explanation:

impulse=mvt

impulse=

$0.20 \times 10 \times 1.2$

impulse=2.4 kgm/ss

Answer 2

Explanation:

impulse= force×time

force=m×a

a= (v-u)÷t

then

acceleration = (1.2-0)÷10= 0.12

now impulse= 0.20×0.12×10= o.24
