a kicker punts a football 3 feet above the ground with an initial velocity of 47 feet per second.

Question

there are three queswtions that go with it

1) write an equation that gives the height (in feet) of the football as a function of the time (in seconds) since it was punted.

2) find the height (in feet) of the football 2 seconds after the punt

3) calculate how many seconds after the punt the ball would hit the ground

Answer 1

ft/sek is SPEED

tu get hite av ball, need the angel from horizontal the ball start at

ie, need vertikal komponent av VELOSITY

if horizontal, get time tu hit ground from hite=(1/2)gt^2 =3 ft

time=root(2*3/32.2)=root(6/32.2)=root(0.186)=0.4317 sekond
