A rock is thrown upward with a vertical speed of 35 m/s and a horizontal speed of 12 m/s on level ground. How far away does it land?

R = 85.73 m

Explanation:

It is given that,

The vertical speed of a rock,

The horizontal speed of a rock,

We know that,

The vertical speed,

Horizontal speed,

Dividing equation (1) by (2) such that,

Let v is the initial velocity of the projection. So,

We need to find the distance where it will land i.e. the range of the projectile. It is given by the formula as follows :

So, it will land at a distance of 85.73 m.
