A ball is projected horizontally with a velocity of $5m/s$ from the top of a building $19.6m$ high. How long will the ball take to hit the ground

Q. A ball is projected horiontally with a velocity of $5m/s$ from the top of a building $19.6m$ high. The horizontal distance covered by ball take to hit the ground?

Q. From a top of building $19.6m$ high a a ball is projected horizontal after how long does it strike the ground if line joining the projection to the point where it hits the ground makes an $\angle {45}^{\circ }$ with horizontal what is velocity of ball?

Q.

A ball is thrown vertically upwards with a velocity of 20m/s from the top of a multi storey building.The height of the point from where the ball is thrown is 25m from the ground.

(a)How high will the ball rise

(b)How long will it be before the ball hits the ground.

Take g=10m/s

Q. A ball is thrown vertically upwards with a velocity of 20 m $s^{-1}$ from the top of a multistorey building of 25 m high. How high will the ball rise from top of the building? (Take g = 10 m $s^{-2}$).

Q. From the top of a building $80m$ 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 ${45}^o$ with the ground. Initial velocity of projection of the ball is $(g=10m/s^2)$
