Find the speed of a pebble when it is at half distance of its journey from top to bottom, when it is thrown horizontally from top of a tower of height 20m with initial velocity of 10m/s is

For body thrown horizontally from the top of a tower,

A particle of mass 50 g is projected horizontally from the top of a tower of height 50 m with a velocity 20m//s . If g=10m//s^(2) , then find the :-

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 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 ball thrown horizontally with velocity v from the top of a tower of height h reaches the ground in t seconds. If another ball of double the mass is thrown horizontally with velocity 3v from the top of another tower of height 4h it reaches the ground in (seconds)

A body is thrown horizontally with a velocity of v m/s from the top of a tower of height 2h reaches the ground in 't' seconds. If another body double the mass is thrown horizontally with a velocity 5v m/s from the top of another tower of height 8h it reaches the ground in a time of

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 is thrown horizontally with a velocity of v m/s from the top of a tower of height 2h reaches the ground in 't' seconds. If another body double the mass is thrown horizontally with a velocity 5v m/s from the top of another tower of height 8h. In the above problem if the first reaches the ground at a horizontal distance 'x' the second body reaches the ground at a horizontal distance

A ball is thrown from a point in level with velocity u and at a horizontal distance r from the top os a tower of height h . At what horizontal distance x from the foot of the tower does the ball hit the ground ?

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
