A batsman hits back a ball straight in the direction of the bowler without changing its initial speed of 12 m s^(-1) . If the mass of the ball is 0.15 kg, determine the impulse imparted to the ball.(Assume linear motion of the ball)

Answer»

Solution :Mass ofball m= 0.15kg andinitialvelocityof ball `v_(0)= -12ms^(-1)`
Finalvelocityafterhittingv= 12 `ms^(-1)`
impulseof force`=m DELTA v `
`=0.15(v-v_(0))`
=0.15[1212]
=3.6 Ns
DIRECTIONOF impulseis from BATSMAN to bowler.
