A ball is tossed from the window of a building with an initial velocity of `8 ms^-1` at an angle of `20^@` below the horizontal . It strikes the ground 3 s later. From what height was the ball thrown? How far from the base of the building does the ball strike the ground?

A boy throws a ball with a velocity of 15 m/s at an angle of 15° with the horizontal. The distance at which the ball strikes the ground is

A boy throws a ball with a velocity of 15 m/s at an angle of 15° with the horizontal. The distance at which the ball strikes the ground is

A ball is thrown vertically upward from the top of a building 96feet tall with an initial velocity of 80feet per second. The distance S (in feet )of the ball from the ground, after t seconds is S = 96 + 80t − 16t^(2) . After how many seconds does the ball strike the ground.

A ball is thrown with a velocity of 30 ms^(-1) from the top of a building 200m high . The ball makes an angle of 30^(@) with the horizontal . Calculate the distance from the foot of the building where the ball strikes the ground (g=10ms^(-2)) .

From the top of a building , a ball is thrown horizontally. The ball strickes the ground after 5 s at an angle of 60^(@) to the horizontal. Calculate the speed with which the ball was projected .

A ball is thrown from the ground with a velocity of 20sqrt3 m/s making an angle of 60^@ with the horizontal. The ball will be at a height of 40 m from the ground after a time t equal to (g=10 ms^(-2))

A boy playing on the roof of a 10 m high building throws a ball with a speed of 10 m//s^(-1) at an angle of 30^(@) with the horizontal. How far from the throwing point will the ball be at a height of 10 m from the ground?
