Superman reportedly is as "fast as a speeding bullet". A bullet of mass 225g begins at rest and accelerates up to 295m/s in a time of 0.025s. What is the momentum of the bullet as it exits the gun?
-
momentum = mass (kg) x velocity (m/s)
So the momentum of the bullet as it exits the gun is .225 x 295 = 66.375 kg m/s
