An object is projected horizontally from a top of the tower of height `h`.The line joining the point of projection and point of striking on the ground makes an angle `45^(@)` with ground,Then with what velocity the object strikes the ground

From the top of a building 19.6 m high, a ball is projected horizontal. After how long does it strike the ground ? If the line joining the point of projection to the point where it hits the ground makes an angle of 45^(@) with the horizontal, what is the initial velocity of the ball ?

A body is projected horizontally from the top of a tower of height 4.9m with a velocity of 9.8m/s. The velocity with which the body strikes the ground is?

From the top of a tower 20m high, a ball is thrown horizontally. If the line joining the point of projection to the point where it hits the ground makes an angle of 45^(@) with the horizontal, then the initial velocity of the ball is:

From the the top of a tower 19.6 m high, a ball is thrown horizontally. If the line joining the point of projection to the point where it hits the ground makes an angle of 45^(@) with the horizontal, then the initial velocity of the ball is:-

A boy kicks a football horizontally from the roof of a building of height 10m, . If the line joining the initial position of the football and the point where it hits the ground make an angle of 45^(@) with the ground, then find the displacement of the football

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))

A body is thrown horizontally from the top of a tower. It reaches the ground after 4s at an angle 45^(@) to the ground. The velocity of projection is

An object is thrown horizontally from a tower H meter high with a velocity of sqrt(2gH) m/s. Its velocity on striking the ground will be :

The initial velocity of a projectile at the point of projection is 3hat i+4hat j ms^(-1) .Then the velocity of striking on the ground is
