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

For body thrown horizontally from the top of a tower,

For body thrown horizontally from the top of a tower,

For body thrown horizontally from the top of a tower,

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 :

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.
