A ball thrown horizontally with velocity v from the top of a tower of height h reaches the ground in t second.If another ball of double mass is thrown horizontally with velocity 2v from the top of another tower of height 9h then it reaches the ground in time (second)?

A body of mass m thrown horizontally with velocity v, from the top of tower of height h touches the level ground at a distance of 250m from the foot of the tower. A body of mass 2m thrown horizontally with velocity v//2 , from the top of tower of height 4h will touch the level ground at a distance x from the foot of tower. The value of x is

A body of mass m is projected horizontally with a velocity v from the top of a tower of height h and it reaches the ground at a distance x from the foot of the tower. If a second body of mass 2m is projected horizontally from the top of a tower of height 2h, it reaches the ground at a distance 2x from the foot of the tower. The horizontal velocity of the second body is :

A body of mass m is projected horizontally with a velocity v from the top of a tower of height h and it reaches the ground at a distance x from the foot of the tower. If a second body of mass 2 m is projected horizontally from the top of a tower of height 2 h , it reaches the ground at a distance 2x from the foot of the tower. The horizontal veloctiy of the second body is.

A ball is thrown horizontally with a speed of 20 m//s from the top of a tower of height 100m Time taken by the ball to strike the ground is

A ball is thrown upwards with speed v from the top of a tower and it reaches the ground with speed 3v .The height of the tower is

A body, rpojected horizontally with a speed u from the top of a tower of height h , reaches the ground at a horizontally distance R from the tower. Another body, projected horizontally from the top of a tower of height 4h , reaches the ground at horizontal distance 2R from the tower. The initial speed of the second body is

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 stone is thrown horizontally with velocity g ms^(-1) from the top of a tower of height g metre. The velocity with which it hits the ground is ("in" ms^(-1))

A ball is thrown upwards with speed ‘v’ from the top of a tower and it reaches the ground with a speed 3v, then the height of the tower is

A ball is thrown vertically upwards from the top of tower of height h with velocity v . The ball strikes the ground after time.
