Question

A cricket ball of mass 150 gm moving with a speed of 12 m/sec is hit by a bat so that the ball is turned back with a velocity of 20m/sec calculate the impulse recived by a ball

Answer 1

19.2. Difference between the K.E. Gives out that. Plz mark it as Brainliest Answer

Answer 2

EXPLANATION:-

We know,

$\sf\;Forece=\frac{impulse}{time}\\\\Impulse=Force\times time\\\\Force\times time=Chnage\;in\;momentum\\\\Change\;in\;momentum=mv-mu\\\\Change\;in\;momentum=0.15(12)-0.15(-20)=4.8\\\\Impulse=4.8\;Ns$
