A stone is thrown vertically upward at a speed of 29.90 m/s at time t=0. A second stone is thrown upward with the similar speed 2.070 sec later.
Find at what time are the two stones at the same height?
Find at what height do the two stones pass each other?
Find the downward speed of the first stone as they pass each other?
