Question

A batsman hits a ball of mass 0.2 kg straight towards the bowler without changing its initial speed of 6 m/s. What is the impulse imparted to the ball?

Options

• 3.2 N-s

• 1.6 N-s

• 4 N-s

• 2.4 N-s

Answer 1

2.4 N-s

Explanation:

The impulse is equals to change in linear momentum.

Change in momentum = m(v - u)

= 0.2(- 6 - 6) = - 2.4

The negative sign shows the direction of impulse is from batsman to bowler.
