Question

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

Answer 1

It is less than its initial speed

Step-by-step 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=√(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.
