A position-time graph is shown below: Position vs. Time 15 Position (cm) -> Time (seconds) -> Which statement accurately describes the motion of the object in the graph above over 10 seconds? The object moves forward at 1 cm/s, stops, and then continues at the same velocity. The object moves forward at 1 cm/s, stops, and then increases velocity to 2 cm/s. The object is at rest for 4 seconds and then moves forward for 4 seconds at 1 cm/s....

1. Draw a correctly labeled motion diagram for each of the following scenarios. Make sure you include both velocity and acceleration vectors a. A car travels along a straight, flat road at a steady speed. b. A truck slows down and comes to a stop as it approaches a red traffic light. c. A train accelerates as it leaves the train station and then keeps moving at a constant speed. d. A bungee jumper jumps from a high bridge. Initially...

cally up from a moving cart. The position of the balls to raph below shows the position of the ball at equal time inter- A ball is fired vertically up from a mo the left of the graph below showst vals, as would be seen by the person on the cart. a. For this person the motion is sym- metric in time so positions on the way down are the same as on the way up, so only one ball...

3. A gun tackle consits of a light rope and two ideal pulleys. One end of the rope is attached to the ceiling and wrapped around both pulleys, as depicted, while the other end is fastned to mass A. Mass B hangs off the pulley that is free to move. The second pulley is attached to the ceiling. Initially the blocks, which have the same mass, are suspended at the same distance from the ceiling and are subsequently released...

PHYSICS HOMEWORK # 26 NEWTON'S LAWS FIRST LAW & FRICTION 24. Two masses are sitting on a horizontal surface as shown to the right. The coefficient of sliding friction between these two masses and the horizontal surface is m-0.520. A string is attached to the end of mas m,8.00 kg. This string is then looped arounda pulley and is finally attached to the left vertical surface. The pulley is attached to mass m 12.0 kg as shown and then a...
