Homework Statement
Height - 15m
Time when ball hits the ground after upward throw 3 s.
I have been trying to find intitial speed with these formulas :
d=v_initial*t-0.5*g*t^2
and
v=v_initial+g*t
Please help to understand how to find initial speed and after what time the ball is at 15m height again.
