Question

Astronauts on our moon must function with an acceleration due to gravity of 0.170g. (a) If an astronaut can throw a certain wrench 12.0m vertically upward on Earth, how high could he throw it on our moon if he gives it the same starting speed in both places? (b) How much longer would it be in motion (going up and coming down) on the moon than on Earth? Please help ASAP, my physics teacher has no clue how to properly teach the methods we need.

Answer 1

Think of gravity in both places as downward acceleration. Using \[s=v_{i}t+\frac{1}{2}at^2\] you should be able to get there. Let me know if that doesn't make sense.

Answer 2

I got something that says math processing error, does that count?
