Asked by Harriet

A rock is thrown into a railroad car standing on a level frictionless track. If the rock has a mass of ms = 1.100 kg and is tossed with a velocity v = 6.3 m/s, how far up will the car go (mc = 5.400 kg) before stopping?

Please explain

the words "into" and "up" , the velocity (with out direction) make this very ill defined.

By up, the railroad car is going up a hill. Sorry if that was unclear
