An automobile with a total mass of 1500 kg is placed on a moving flatbed railcar. (There are no additional horizontal forces acting on the system) The flatbed is 1.20 m above the ground. The railcar is moving eastward at a constant speed of 8.2 m/s and has a mass of 38000 kg. The car accelerates westward and when it leaves the flatcar it is traveling at 23.0 m/s relative to the ground.
(a) What is the speed of the railcar when the car leaves?
(b) What is the distance between the car and the west end of the flatcar, when the car touches the ground?
