Answer:
The momentum of the moving cart is 80kgm/s.
HOW TO CALCULATE MOMENTUM:
The momentum of a body can be calculated by multiplying the mass of that body by its velocity. That is;
Momentum (p) = mass (m) × velocity (v)
According to this question, a 20kg cart moving at 4 m/s will have a momentum as follows:
Momentum (p) = 20kg × 4m/s
Momentum (p) = 80kg*m/s.
- Therefore, the momentum of the moving cart is 80kgm/s.
