Question

A batsman hits back a ball straight in the direction of the bowler without changing the initial speed of 12 m/s if the mass of the ball is0.15 kg determine the impluse imparted to the ball

Answer 1

the impluse =change in momentum ×time
0×0.15=0

Answer 2

${\huge{\underline{\underline{\mathfrak{\purple{♡ANSWER♡}}}}}}$.

✪. Change in momentum=${0.15×12-(-0.15×12)}$

✪. ${3.6Ns,}$

✪. $\red{\bold{\underline{\underline{Impulse}}}}$ = ${3.6Ns,}$

• In the direction from the batsman to the bowler .
• This is an example where the force on the ball by the batsman and the time of contact of the ball and the bat are difficult to know , but the impulse is readily calculated
