Unformatted text preview: sanchez (es25396) Homework #2  Motion in 1D guevara (130101) 1 This printout should have 11 questions. Multiplechoice questions may continue on the next column or page find all choices before answering. 001 10.0 points The plot shows x ( t ) for a train moving along a long, straight track. x t Which statement is correct about the mo tion? 1. The train at first speeds up, then slows down. 2. The train continually speeds up. 3. The train continually slows down and comes to rest. correct 4. The train in fact moves at constant speed along a circular path described by the x ( t ) curve. 5. The train at first slows down, then speeds up. 6. The train moves at constant velocity. Explanation: The slope of x ( t ) continually decreases to reach zero. Since v x ( t ) = dx dt is by definition the slope of x ( t ) at each t , the train continu ally slows down until it stops. 002 (part 1 of 5) 10.0 points The position versus time for a certain object moving along the xaxis is shown. The objectsaxis is shown....
