Asked by Mariah
The place kicker on a football team kicks a ball from ground level with an initial speed of 22.40 m/s at an angle of 15.0° above the horizontal. How far does the ball travel in the x-direction before it lands on the ground again? You may neglect air resistance.

initiual veertical speed: 22.4*sin15
hfinal=hi=0
hfinal=hi+vivertical*time-4.9t^2
solve for time t.
then
horizontal distance=22.4*cos15 * timeinair
hfinal=hi=0
hfinal=hi+vivertical*time-4.9t^2
solve for time t.
then
horizontal distance=22.4*cos15 * timeinair
