Question

A batsman hit back a ball straight in the direction of the bowler without changing its initial speed of 12ms-1 it the mass of the ball is 015kg, determine the implies imparted to the ball

Answer 1

we know that

Impulse = change in momentum

or

I = dp = m (v-u) 

here,

m = 0.15 kg

 u = 12 m/s 

v = - 12 m/s

so,

I = 0.15(-12 – 12)

thus, impulse will be

I = - 3.6 Ns

Answer 2

HLO MATE HERE U GO.

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

Impulse = 3.6Ns in the direction from the batsman to the bowler .
