to win the game, a place kicker must kick a
football from a point 52 m (56.8672 yd) from
the goal, and the ball must clear the crossbar,
which is 3.05 m high. when kicked, the ball
leaves the ground with a speed of 25 m/s at
an angle of 35.9° from the horizontal.
the acceleration of gravity is 9.8 m/s.
by how much vertical distance does the ball
clear the crossbar?
answer in units of m.

i’m really confused me understand these steps for my quiz!

2.47 m

Explanation:

Let's calculate first the time it takes for the ball to cover the horizontal distance that separates the starting point from the crossbar of d = 52 m.

The horizontal velocity of the ball is constant:

and the time taken to cover the horizontal distance d is

So this is the time the ball takes to reach the horizontal position of the crossbar.

The vertical position of the ball at time t is given by

where

is the initial vertical velocity

g = 9.8 m/s^2 is the acceleration of gravity

And substituting t = 2.56 s, we find the vertical position of the ball when it is above the crossbar:

The height of the crossbar is h = 3.05 m, so the ball passes

above the crossbar.
