1. The problem statement, all variables and given/known data For the same initial upward velocities, how many times higher will an object travel above the lunar surface (g=1.6 m/s^2) than above the surface of Earth? Assume air resistance is negligible. 2. Relevant equations delta Y = v1y^2 X 10^2 + 1/2 X 9.8 m/s^2 X (10)^2 3. The attempt at a solution I assumed that initial velocity should be zero for both Earth and Moon. I specified time to be 10 seconds. For Earth: delta Y = 0 X 10^2 m/+ 1/2 X 9.8 m/s^2 X (100) = 1/2 X 9.8 s^2 X (100) = 490 m For Moon: delta Y = 0 X 10^2 m/+ 1/2 X 1.6 m/s^2 X (100) = 1/2 X 1.6 s^2 X (100) = 80 m So am I doing this right? Because I think my final answer would be that the object would be 6 times higher above the lunar surface than the surface above the Earth. Somebody please help me. Thanks.
