Question: A 10-kg rock and a 20-kg rock are thrown upward with the same initial speed v0 and experience no significant air resistance.
A- If the 10-kg rock reaches a maximum height h, what maximum height will the 20-kg ball reach?
I have been stuck on this question for a long time, please help. Show steps. Thanks!
