Question

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