football kickedfrom 63 yards away from goalpost that is 10 feet above the ground. If the initial speed of the football is 15 m/s, and it's kicked at a 45 degree angle, will it clear the uprights?

Step 1

A football is projected with a velocity of 15 m/s at an angle of 45° from a height of 10 feet above the ground. Consider that the parameters below the level at which the football is projected are negative. So, the initial height of the football is -10 feet.

Step 2

The initial velocity in the horizontal direction is:

(15 m/s)cos 45°
10.61 m/s
