A particle is thrown from the top of a tower of height `h` with speed `v_0` at an unknown angle. Find the speed with which it strikes the ground.

A particle is dropped from the top of a tower of height 80 m . Find the time of jurney and the speed with which it strikes the ground.

A particle is projected from the top of a tower of height h with a speed u at an angle theta above the horizontal . T_(1) =Time taken by the projectile to reach the height of tower again . T_(2) =Time taken by the projectile to move at right angle to initial direction of motion . V_(1) =Speed of the projectile when it moves at an angle theta//2 with the horizontal . V_(2) =Speed with projectile strikes the ground . .

In the figures shown, three particles are thrown from a tower of height 40 m as shown in figure. In each case find the time when the particles strike the ground and the distance of this point from foot of the tower. , , .

A ball is thrown horizontally with a speed of 20 m//s from the top of a tower of height 100m velocity with which the ball strikes the ground is .

A ball is thrown horizontally with speed 10 m//s from the top of tower of height 80 m . After how much time and at what horizontal distance from the tower it strikes the ground ?

A stone is thrown from the top of a tower at an angle of 30^(@) above the horizontal level with a velocity of 40 m/s. it strikes the ground after 5 second from the time of projection then the height of the tower is
