A rock thrown with a certain speed from the top of a cliff will enter the water below with a speed that is the same whether the rock is thrown horizontally or at any angle. Discuss.

For body thrown horizontally from the top of a tower,

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 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 stone thrown upward with a speed u from the top of a tower reaches the ground with a velocity 4u. The height of the tower is

A stone is thrown vertically upwards with an initial speed u from the top of a tower, reaches the ground with a speed 3 u . The height of the tower is :

Three identical balls are thrown from the top of a building, all with the same initial speed. As shown in figure., the first ball is thrown horizontally, second above horizontal level, and third at an angle below the horizontal. Neglecting air resistance, rank the speeds of the balls at the instant each hits the ground.

Two balls are thrown with the same speed V_(0) = 10 m/s from the top of a cliff. The angle of their initial velocities are theta =15° above and below the horizontal, as shown in figure. The two balls hit the ground at points 'A' and 'B'. The distance AB (in m) is? Given height of cliff = 50 m. g=10m/ s^(2) .

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 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 .
