A 1 kg block on a spring is stretched out 0.5 meters. What will its speed be when it reaches its equilibrium point? The spring constant is 100N/m. The Bellagio is about 150 meters tall. A person drops a penny off the roof. The penny is 1 kg. How fast will it be going when it hits the ground?

An experiment was performed on a 2-kg block. forces of 5, 10 and 15 newtons respectively were applied to the block for 5 seconds. describe the difference in acceleration between the three trials. a) the final accelerations will all be the same. b) the final acceleration will triple between the first and third trial. c) the final acceleration will be cut by 1/3 from the first to third trial. d) the final acceleration will increase nine time between the first and third trial.
