At what speed would an 8.0 kg trash can have a momentum of 120,000 kgm/s?
Question
At what speed would an 8.0 kg trash can have a momentum of 120,000 kgm/s?
Solution
The momentum of an object is calculated by the formula:
Momentum = mass * velocity
We can rearrange this formula to solve for velocity:
Velocity = Momentum / mass
Given that the momentum is 120,000 kgm/s and the mass is 8.0 kg, we can substitute these values into the formula:
Velocity = 120,000 kgm/s / 8.0 kg = 15,000 m/s
So, the trash can would need to be moving at a speed of 15,000 m/s to have a momentum of 120,000 kgm/s.
