Question

Jules kicks a soccer ball off the ground and into the air with an initial velocity of 25 feet per second. Assume the starting height of the ball is 0 feet. Approximately, how long does it take until the soccer ball hits the ground again?

A. 0.6 sec

B. 0.8 sec

C. 1.6 secs

D. 2.8 secs

Answer 1

use one of the equations for constant acceleration
acce.eration in this case is due to gravity and is -32 ft/sec^2
you have initial ve,city u = 25, g = -32, and displacement s = 0 , t = ?

Answer 2

use
s = ut + 0.5gt^2

Answer 3

I got it thank you
