Hello, I'm having a bit of trouble starting this problem:
A ball is dropped from a height of 30 m. At the same instant another ball is thrown straight up from the ground with aspeed of 30 m/s. How long are the balls in the air before they reach the same height?
I'm not sure what equation to use here. Any help would be appreciated. Thanks in advance.
