Alright I am obviously retarded since I am unable to figure this question out.
The question is:
You have just landed on Planet X. You take out a ball of mass m, release it from rest from a height of h and measure that it takes a time of t to reach the ground. You can ignore any force on the ball from the atmosphere of the planet.
My guess as to what the answer would be is: m*((h/t)/t)
since weight equals mass times acceleration and the acceleration equals change in velocity over time. I figured it starts at 0 and ends at h, so the change in velocity is h/t. Where am i going wrong with this?
The error or hint I am receiving is "Your answer is off by a multiplicative factor."
Anyone have any ideas? I have to answer this problem within the next 2 hours and I still can't figure it out. I would try changing my original answer above a bit, but if I guess anymore I get zero credit for the problem.
