A ball is thrown horizontally from the top of a tower and strikes the ground in `3 s` at an angle of `30^@` with the vertical.
(a) Find the height of the tower.
(b) Find the speed with which the body was projected.

A body is thrown horizontally from the top of a tower and strikes the ground after three seconds at an angle of 45^@ with the horizontal. Find the height of the tower and the speed with which the body was projected. (Take g = 9.8 m//s^2)
