A person standing at the edge of a seaside cliff kicks a stone over the edge?
A person standing at the edge of a seaside cliff kicks a stone over the edge with a speed of vi = 19 m/s. The cliff is h = 50 m above the water’s surface.
How long does it take for the stone to fall to the water? (s)
With what speed does it strike the water? (m/s)
vo= initial velocity in the j/y direction =0
g= 9.81j m/s^2
h= 0.5gt^2 +vo*t
t= sqrt(2h/g)
t= 3.19 s
Vf^ 2=Vo^2 +2gh
Vf = sqrt(2gh)
Vf=31.32 m/s
