A stone is projected horizontally from the top a tower with a speed of 5m/s.It lands on the ground level at a horizontal distance of 20m from the foot of the tower.Calculate the height of the tower.(g=10m/s2)
Answered by bobpursley
g=10m/s^2 ????? Nowhere on the Earth is it that high, why would a teacher tell you to use that? Why not 14m/s^2?

time in air:
20m=5m/s *t
t=4sec

hf=hi+v<sub>vertical</sub>*t-4.9t^2

0=hi+0*4 -4.9(4^2)

hi= ??
