A soccer player kicks a ball with a speed of 30 m/s at an angle of 10°. How long does the ball stay in the air?

3.763 Seconds

Explanation:

The vertical component of the ball's speed is 30 sin(10°) = 5.209 meters per second.

The acceleration of gravity is 9.8 meters per second² downward.

The ball continues to rise for 9.8/5.209 = 1.881 seconds after the kick.

it begins to fall, and takes the same length of time to return to the ground when it was kicked.

So the time between the kick and return to the ground is (2 x 1.881) = 3.763 seconds.
