a batsman hits back a ball straight in the direction of a bowler without changing its initial speed of 12 m per second if the mass of the ball is 0.15 kilogram determine the impulse imparted to the ball

Impulse (J) = Force (F) × time (t) = Change in Momentum (∆p)
u = - 12 m/s
v = 12 m/s
m = 0.15 kg
∆p = m(v - u)
J = 0.15 kg (12 -(- 12)) m/s
J = 0.15 kg × 24 m/s
J = 3.6 kg·m/s.

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

✪. {3.6Ns,}

✪. \orange{\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
