The hang time of a football kicked at a speed of 18 m/s and an angle of 65 degrees is calculated using projectile motion principles. The vertical component of the initial velocity is determined to be approximately 16.3 m/s. The time taken for the football to reach its peak height is 1.66 seconds, necessitating a multiplication by two to account for the descent, resulting in a total hang time of 3.32 seconds.
PREREQUISITESStudents studying physics, educators teaching projectile motion concepts, and sports analysts interested in the dynamics of ball trajectories.
If it takes 1.66 seconds for the vertical component of velocity to become zero, then you do need to multiply by two.stephi said:Homework Statement
A football is kicked with a speed of 18 m/s at an angle of 65 degrees to the horizontal. What is the hang time of the football?

The Attempt at a Solution
i thought the answer was 1.66. but do i need to multiply that by 2 to get the full hang time?
