The initial momentum of the boy is 0 kgm/s the right option is A. 0 kgm/s.
<h3>What is momentum?</h3>
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:
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
Hence, The initial momentum of the boy is 0 kgm/s the right option is A. 0 kgm/s.

Answer:
No state of matter is required
Explanation:
When <em>radiant energy </em>is the source, we are talking about <em>energy transfer by radiation, </em>so matter is not needed for the energy to be transfered.
An example of this could be the Sun, it heats up the Earth by radiation, even through the vacuum of outer space, where there is next to no matter.
