Q1. A 67 kg man weighs 637 N on the Earth's surface. How far above the surface of the Earth would he have to go to "lose" 19 percent of the body weight?

Q2. A 64g ice cube can slide without friction up and down a 35 degree slope. The ice cube is pressed against the spring at the bottom of the slope, compressing the spring 12cm. The spring constant is 27 N/m .When the ice cube is released, what distance will it travel up slope before reversing direction?
