A 50 slug car can accelerate from 0 to 50 ft/s while traveling 1000 feet. The car then stops, and a passenger gets in. Now the car can accelerate from 0 to 50 ft/s while traveling 1050 feet. What is the weight of the passenger?

M1 and M2

A mass, m1, accelerates at 3 m/s2 when a force, F, is applied. A second mass, m2, accelerates at 1.0 m/s2 when F is applied to it.
