13. bari kicked a ball and its leaves the ground at an angle 30° with a velocity of 20 m/s.
find hang time of the ball
11 pari iricked a ball and its leaves the ground at an angle 30° with a velocity of 20. m/s.

i have a physics test upcoming and i’m particularly stuck on this question and i would be grateful if anyone could me out.

The hang time is 2.04 seconds

Explanation:

2-D Motion

It referred to as a situation where an object is launched in such a way it describes a curve, reaches a top height and then returns to ground level after traveling a certain distance x away from the launch point.

Let be the launching speed forming an angle with the horizontal reference. The hang time (time the object remains in the air) is given by

Since

Then

We'll use the given values

The hang time is 2.04 seconds
