A football is kicked at ground level with a speed of 20.7 m/s at an angle of 34.6° to the horizontal. How much later does it hit the ground?

Answer 1

The vertical velocity component, Voy, determines how long it takes to hit the ground.

Voy = 20.7 sin34.6 = 11.75 m/s

It hits the ground when t = 2 Voy/g
(That is, Voy/g to go up, and Voy/g to come back down from maximum height.)

Comp[ute 2 Voy/g

Answer 2

.417s
