A student measures the velocity of an object moving along a track. At time t = 0 s, the object is moving at a constant 4.0 m/s in the positive x-direction. At time t = 3.0 s, the object begins to slow, stops at t = 5.0 s, and then moves in the opposite direction. At t = 6.0 s, the object as reached a speed of -2.0 m/s. It moves at this speed until the student quits taking data...
