A .145kg baseball is thrown at 40 m/s (~89.5mph). What is the momentum of the baseball?
p = mv = .145kg * 40m/s = 5.8 kg-m/s
116 J
To calculate the momentum of an object, you need to use the formula:
Momentum (p) = mass (m) × velocity (v)
Given that the mass of the baseball is 0.145 kg and the velocity is 40 m/s, we can substitute these values into the formula to find the momentum.
p = 0.145 kg × 40 m/s
Now, let's evaluate the expression:
p = 5.8 kg·m/s
Therefore, the momentum of the baseball is 5.8 kg·m/s.
