Afootball is kicked from ground level with an initial velocity of 22.0 m/s at angle of 58.5° above the horizontal. how long, in seconds, is the football in the air before it hits the ground? ignore air resistance. seconds

3.82 s

Explanation:

The football follows a projectile path, where the x-component of the velocity will remain constant, and the y-component of the velocity will vary because of gravity.

The time elapsed before the ball hits the ground is 2 times the time for the ball to reach  its maximum height, which is also the time necessary for the vertical velocity of the ball to go from its original value to 0:

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.
