The initial momentum of the boy is 0 kgm/s the right option is A. 0 kgm/s.

What is momentum?

Momentum can be defined as the product of mass and velocity. The S.I unit of momentum is kgm/s.

The initial momentum of the boy can be calculated using the formula below.

Formula:

  • M' = mu

Where:

  • M = Initial momentum of the boy

From the question,

Given:

  • M = mass of the boy = 60 kg
  • U = Initial velocity of the boy = 0 m/s (at rest)

Substitute these values into equation 1

  • M = 60(0)
  • M = 0 kgm/s

Hence, The initial momentum of the boy is 0 kgm/s the right option is A. 0 kgm/s.
