A boy stands at 39.2 m from a building and throws a ball which just passes through a window 19.6 m above the ground. Calculate the velocity of projection of the ball.

A boy stands 19.6 m away from a 9.8m high cliff. If the throws a ball towards the cliff such that it just passes above from it , find the velocity of projection of the ball.

A ladder, 25 m long reaches a window of building 20 m, above the ground. The distance of the foot of the ladder from the building.

A cricketer can throw a ball to a maximum horizontal distance of 100 m. How high above the ground can the cricketer throw the same ball ?

Two tall buildings are 40m apart. A ball thrown horizontally from a window 145m above the ground in one building is to enter a window 22.5m above the ground in the other building.The speed of the ball should be (A) 6m/s (B) 8m/s (C) 10m/s (D) 12m/s

From the top of a building 80 m high, a ball is thrown horizontally which hits the ground at a distance.The line joining the top of the building to the point where it hits the ground makes an angle of 45^(@) with the ground. Initial velocity of projection of the ball is (g=10 m//s^(2))
