A ball is thrown horizontally from a height of `20m`.If hits the ground with a velocity of `3` times the velocity of projection.The velocity of projection is `3.5x m//s` then `x` is

5A ball is thrown horizontally from a height of 20 m. It hits the ground with a velocity three times its initial velocity. The initial velocity of ball is

A ball is projected horizontally. After 3s from projection its velocity becomes 1.25 times of the velocity of projection. Its velocity of projection is

A ball is projected horizontally. After 3s from projection its velocity becomes 1.25 times of the velocity of projection. Its velocity of projection is

A ball is projected horizontally. After 3s from projection its velocity becomes 1.25 times of the velocity of projection. Its velocity of projection 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))

A ball is thrown vertically upward attains a maximum height of 45 m. The time after which velocity of the ball become equal to half the velocity of projection ? (use g = 10 m//s^(2) )
