Question

When a football in a field goal attempt reaches its maximum height, how does its speed compare to its initial speed?

Answer 1

Answer:

It is less than its initial speed

Explanation:

The football moves both horizontally and vertically at the same time with a diagonal velocity v. This velocity vector v has two components: the horizontal velocity $v_x$, and vertical velocity $v_y$:

$v=\sqrt{v_x^2+v_y^2}$

When the football reaches its maximum height, the vertical velocity is zero, leaving only the x component. So, its speed it is less than its initial speed.
