What's the momentum of a 3.5-kg boulder rolling downhill at 5 m/s?
9. What's the momentum of a 3.5-kg boulder rolling downhill at 5 m/s?
To find the momentum of an object, you can use the formula:
Momentum = mass × velocity
In this case, the mass of the boulder is given as 3.5 kg, and the velocity is given as 5 m/s.
So, to find the momentum, simply multiply the mass by the velocity:
Momentum = 3.5 kg × 5 m/s
Now calculate the product:
Momentum = 17.5 kg·m/s
Therefore, the momentum of the 3.5-kg boulder rolling downhill at 5 m/s is 17.5 kg·m/s.
