This is a trick question, in a way. You can go through the math of height and speed, using an unknown acceleration (you will find that this fails to have a solution when g=9.8 is used).
Or, you can just note that since momentum is conserved, the speed at launch is exactly the same as the speed at impact: 24 m/s
Given: A rock is thrown upward from the surface of a planet at 24m/s. It reaches a maximum height of 180 meters.
Question: How fast is the rock falling when it lands on the planet?
I am honestly dumbfounded by this problem. I feel that I don't have enough information, I don't even know where to approach. Shouldn't there be a position function?
Any input is appreciated. Thank you
