6. A ball that weighs 40 pounds on earth is dropped 100 ft on Mars, what is the PE energy just before you drop the ball? (gravity on Mars is 12.1760 ft/s) 7. If you drop an object that weighs 75 pounds on earth from 1000 ft on Jupiter, what is the ball's velocity right before impact? (gravity on Jupiter is 81.3320 ft/s)
