A football is kicked at ground level with a speed of 19.8 m/s at an angle of 33.8° to the horizontal. How much later does it hit the ground?
Football 2D Motion: Time in Air
Click For Summary
SUMMARY
The discussion centers on calculating the time a football remains in the air after being kicked at a speed of 19.8 m/s and an angle of 33.8° to the horizontal. The user initially struggled with two unknown variables: the horizontal distance (x final) and time (t). Ultimately, the user resolved the issue independently, indicating a successful understanding of projectile motion principles.
