Two projectiles are projected simultaneously from the top and bottom of a vertical tower of height `h` at angles `45^(@)` and `60^(@)` above horizontal respectively.Body strike at the same point on ground at distance `20m` from the foot of the tower after same time.
The speed of projectile projected from the bottom is

Two projectiles are projected simultaneously from the top and bottom of a vertical tower of height h at angles 45^(@) and 60^(@) above horizontal respectively.Body strike at the same point on ground at distance 20m from the foot of the tower after same time. The time of flight of projectles is

Two projectiles are projected simultaneously from the top and bottom of a vertical tower of height h at angles 45^(@) and 60^(@) above horizontal respectively.Body strike at the same point on ground at distance 20m from the foot of the tower after same time. The ratio of the speed of the projectile projected from the top and the speed of the projectile projected from the bottom of tower is

A body thrown horizontally from the top of a tower touches the ground at a distance of 160 m from the foot of the tower. If the velocity of projection is 40 m/s then the height of the towers is

A body thrown horizontally from the top of a tower touches the ground at a distance of 160 m from the foot of the tower. If the velocity of projection is 40 m/s then the height of the towers is

Shots are fired from the top of a tower and from bottom simultaneously at angle 30^(@) and 60^(@) as shown. If horizontal distance of the point of collision is at a distance 'a' from the tower. Then height of tower h is

A vertical tower stands on a horizontal plane, and from a point on the ground at a distance of 30 metres from the foot of the tower , the angle of elevation is 60^@ . The height of the tower is

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

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

A body thrown horizontally from the top of a tower touches the ground at a distance of 160m from the foot of the tower.If the velocity of projection is 40m/s then the height of the tower is (g=9.8m/s^(2))
