If Two bodies of same mass is thrown from top of a tower with same speed simultaneously.one (x) is thrown vertically downward and another(y) is thrown horizontally then what will happen?

When two bodies of the same mass are thrown from the top of a tower with the same speed simultaneously, one vertically downward (x) and the other horizontally (y), different motions will occur due to gravity's influence. Let's break down what will happen to each body.

For Body x:
- Body x is thrown vertically downward. Due to the force of gravity acting downwards, it accelerates in the downward direction.
- The vertical motion of Body x can be described using the equations of motion, such as s = ut + ½at², where s is the displacement, u is the initial velocity, t is the time, and a is the acceleration.
- In this case, the initial velocity u and the time t are crucial in determining the displacement of Body x.

For Body y:
- Body y is thrown horizontally, which means that its initial vertical velocity is zero.
- However, it still has an initial horizontal velocity that remains constant throughout its motion until it lands on the ground.
- The horizontal motion of Body y can be described using equations of uniform motion, such as s = ut, where s is the displacement, u is the initial velocity, and t is the time.
- In this case, the initial velocity u and the time t are crucial in determining the horizontal displacement of Body y.

In summary, when the two bodies are thrown simultaneously:
- Body x will experience vertical motion, accelerating downwards due to gravity.
- Body y will experience horizontal motion, moving with a constant horizontal velocity.

Keep in mind that the actual values and specific outcomes would depend on several factors like the height of the tower, the magnitude of the initial speed, the timing of the throw, and other forces acting on the bodies such as air resistance.
