Answer:
We conclude that the required momentum is 80 kgm/s.
Explanation:
Given
- Mass m = 20 kg
- Velocity v = 4 m/s
To determine
The momentum p = ?
Important Tip:
- The momentum of an object is the product of mass and velocity.
We can determine the momentum using the formula
where
- p is the momentum
- m is the mass
- v is the velocity
now substituting m = 20 and v = 4 using the equation
kg m/s
Therefore, we conclude that the required momentum is 80 kgm/s.
