Final answer:
Your hangtime refers to the amount of time you remain in the air after jumping. To calculate your hangtime using the equation for free-fall distance, you cannot simply plug in the height you can jump. Instead, you would need to measure the time it takes for you to reach your maximum height and then double that time to determine the total hangtime.
Step-by-step explanation:
Your hangtime refers to the amount of time you remain in the air after jumping. To calculate your hangtime using the equation for free-fall distance, you cannot simply plug in the height you can jump. This is because the equation assumes that the object was launched from a height and returns to the same height. In the case of jumping, your starting point is the ground and your ending point is also the ground, so the height value for the equation would be zero.
To calculate your hangtime using the free-fall equation, you would need to measure the time it takes for you to reach your maximum height and then double that time to determine the total hangtime.
