What is the momentum of a 0.145 kg baseball traveling at 40.0 m/s

5.8 kg m/s

Identify the given information.
m = 0.145 kg
v = 40.0 m/s

Choose which formula you should use. In this case, you are finding momentum.
p = mv, where p is momentum.

Substitute and solve.
p = 0.145 kg x 40.0 m/s
p = 5.8 kg m/s

Centrapedial force is the answer
