3 Select the THREE responses that are correct. 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....
