If a football is kicked in the air from the ground, and it takes 2 seconds to reach a height of 94 feet, what was the initial vertical velocity of the football?

30 feet per second

158 feet per second

79 feet per second

15 feet per second

79 feet per second :)

s = ut + 0.5at²

94 = 2u + 0.5(-32)(2²)

2u = 158

u = 79 feet/second

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
