A cricket ball of mass 160 g is bowled at 40 m·s−1 towards a batsman. Calculate the momentum of the cricket ball.

Chipa Thomas Maimela‘s insight:

Identify what information is given and what is asked for

The question explicitly gives

the mass of the ball (m = 160 g = 0,16 kg), and the

Identify what information is given and what is asked for

The question explicitly gives

  • the mass of the ball (m = 160 g = 0,16 kg), and
  • the velocity of the ball  = 40 m·s−1 towards the batsman)

To calculate the momentum we will use

Do the calculation

Quote the final answer

The momentum of the cricket ball is 6,4 kg·m·s−1 in the direction of the batsman.
