Question

Elaina Kicks A Soccer Ball With An Initial Velocity Of

Answer 1

By using the motion equations, we conclude that she will make the goal.

Will she make the goal?

First, we know that the goal is 20ft away, and the position in x is given by:

$x = 28*cos(58)*t$

Let's find the time in which the ball will travel these 20 ft.

$20 = 28*cos(58)*t$

$(20)/(28*cos(58)) = t = 1.35$

So the horizontal distance is covered in 1.35 seconds, now let's see which is the height of the ball at that time.

The height equation is:

$y = -16*t^2 +28*sin(58)*t$

Evaluating in t = 1.35 we get:

$y = -16*(1.35)^2 +28*sin(58)*1.35\\\\y = 2.9$

And the goal is 5ft tall, so we can conclude that she will make the goal.
