ombined mass of 200 kg and are zooming along at 10 m/s in a 100 kg amusement
car. they bump into melinda's car, which is sitting still. melinda has a mass of 25 kg and is also
in a 100 kg car. after the collision, the twins continue moving with a speed of 4.12 m
a. what is the initial momentum of the system?
nitial momentum is zero
b. what must be the final momentum of the system?
c, how fast is melinda's car bumped across the floor?
