From the top a building 39.2 m high, a ball is thrown by a velocity of 19.6 m/s in the downwards direction making an angle of `30^@` with the horizontal. Find the time ball takes to hit the ground and the horizontal range. g= 9.8 m/`s^2`

From the top of a cliff 73.5 m a body is projected with a velocity of 19.6 m/s at an angle of 30^@ with the horizontal. Determine the time of flight, the distance from the foot of the tower and velocity with which the body strike the ground. g =9.8 m/ s^2

A projectile is thrown with a speed of 25 m/s in a direction 30^@ above horizontal. Find the height to which it rises, the time of flight and the horizontal range.

Calculate the horizontal range covered by a stone thrown with velocity of 30m//s inclined at an angle of 45^@ with the horizontal Assume g=9.8m//s^2
