Asoccer ball is kicked at 8m/s. it lands on the ground after being in the air for .85 seconds. at what angle is it kicked?

If ball remains in air for total time T = 0.85 s

this is also known as time of flight

In order to find the time of flight we can use kinematics

so for complete motion its displacement in y direction will be zero

now we know that net velocity of the ball is 8 m/s

while is y direction component we got is vy = 4.165 m/s

now by component method we can say

so it is projected at an angle of 31.4 degree above horizontal

there are no correct statementd on the list of choices you provided.

the answer is a 3.8cm
