A proposed ride at the Valley Fair amusement park launches a roller coaster car up an inclined track. Near the top of the track, the car reverses direction and rolls backwards into the station. As a member of the safety committee, you have been asked to compute the acceleration of the car throughout the ride and determine if the acceleration of an object moving up a ramp is different from that of an object moving down the same ramp. To...

If an object's position versus time graph is a straight line with a positive slope, then that object is moving with a constant velocity. moving with zero acceleration. moving upward. moving with a constant speed. moving with a constant, non-zero acceleration.4 An object can reverse its direction of travel when it has a constant acceleration. True False 5 Let us take up to the positive direction. If you throw a small rock straight up and catch it when it returns to you, its velocity vs....
