A football is kicked from a tee to start the football game. If the ball is kicked at a 38 degree angle with an initial velocity of 27.1 m/s, Find the maximum height of the football as it flies through the air.
I was using these equations:
Voy = Vo(sine of theta)
Vy = Voy + at
y = 1/2(a)(t^2)
My attempt:
Voy = 27.1(sin38)
Voy = 27.1(.62)
Voy = 16.68
-16.68 = 16.68 + -9.8t
-33.36 = -9.8t
t = 3.4
y = 1/2(-9.8)(3.4^2)
y = -56.644
Lon Capa only wants a less than three digit answer, and it keeps saying that it's wrong. I've tried -56 m, 56 m, -57 m, and 57 m. Please help.
