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

To analyze the motion of a body that is traveling along a curved path, to determine the body's acceleration, velocity, and position. A motorcyclist travels around a curved path that has a radius of 250 ft.

You walk with a velocity of 2 m/s north. You see a man approaching you, and from your frame of reference he has a speed of 3 m/s to the south.

Imagine you are holding an apple. Does this apple have energy? how do you know?
