A woman of mass m = 63 kg runs at a velocity vi = 1.53 m/s before jumping on a skateboard that is initially at rest. After jumping on the board the woman has a velocity vf = 1.42 m/s.b. What is the mass of the skateboard in kilograms? mb =c. The woman soon loses his balance and falls backwards off the board at a velocity of 1.0 m/s. Assuming momentum is conserved in this process, what is the skateboard's new velocity in meters per second? [Note: this may not be a very good assumption, as there can be significant friction in the ball bearings of the skateboard]

moving 0.15 m/s in the opposite direction, and they stick together. Find the velocity of the engine-car
combination as they move off together. Assume "to the right" is the positive direction.
