The nucleus is made up of the protons (which have a positive charge) and neutrons and surrounded by a cloud of electrons ( which have a negative charge ).
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.
