I am having trouble with this one. for all the formulas I tried I need the velocity, which they don't tell us in the problem. Any help would be appreciated .
A stone falls from rest from the top of a cliff.
A second stone is thrown downward from the
same height 2.4 s later with an initial speed of
47.04 m/s. They hit the ground at the same
time.
The acceleration of gravity is 9.8 m/s2 .
How long does it take the first stone to hit
the ground? Answer in units of s.
How high is the cliff? Answer in units of m.
