Train cars are coupled together by being bumped into one another. Suppose two loaded train cars are moving toward one another, the first having a mass of 180,000 kg and a velocity of 0.300 m/s, and the second having a mass of 125,000 kg and a velocity of -0.120 m/s. (The minus indicates direction of motion.) What is their final velocity (in m/s)? (Enter a number.) m/s

What is the momentum of a 10Kg object that slides at 12m/s across an icy lake?.

Suppose a pitcher throws a ball of 0.15kg with a momentum that equals that of a 2g bullet with a speed of 1800m/s. What is the speed of the ball in km/h?
