Homework Statement
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.
Homework Equations
delta Y = v1y^2 X 10^2 + 1/2 X 9.8 m/s^2 X (10)^2
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.
