Question

A ball is thrown horizontally from the top of a building. How far will the ball fall in 2.00 seconds?

Answer 1

`s = 19.6 m`

Explanation:

The horizontal throw causes no difference in vertical distance. The result would be identical to the result in a situation in which the ball is simply dropped.

Use the formula

`s = u*t + (1/2)*a*t^2`

where the variables `s, u, and a` refer to the vertical direction. The variable `u = 0` since the ball was not thrown down or up.

`s = 0 + (1/2) * 9.8 m/s^2 *(2 s)^2 = 19.6 m`

I hope this helps,
