A stone is thrown from the top of a tower of height 50 m with a velocity of 30 m per second at an angle of `30^(@)` above the horizontal. Find (a) the time during which the stone will be in air, (b) the distance from the tower base to where the stone will hit the ground, (c) the speed with which the stone will hit the ground, (d) the angle formed by the trajectory of the stone with the horizontal at the point of hit.

Answer

[(a) 5.0 s, (b) `75 sqrt3 m` (c) 43.58 m/s, (d) `tan^(-1) ((7)/(3 sqrt3))]`
