Question

A batsman hit back a ball straight in the direction of the bowler without changing its initial speed of. 12 ms -1. If the mass of the ball is 0.15 kg, The impulse imparted to the ball is (A) 2.8 Ns (B) 3.6 Ns (C) 3.9 Ns (D) 4.2 Ns

Tardigrade Admin · Accepted Answer

Change in momentum =(0.15 × 12)-(-0.15 × 12) =3.6 Ns ⇒ Impulse =3.6 Ns

Q. A batsman hit 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 $0.15 k g$ , The impulse imparted to the ball is

2.8 Ns

3.6 Ns

3.9 Ns

4.2 Ns

Change in momentum
$= (0.15 \times 12) - (- 0.15 \times 12)$
$= 3.6 N s \Rightarrow$ Impulse $= 3.6 N s$
