Answer:
a. less than 1 second.
Step-by-step explanation:
The hang time, or the time one's feet are off the ground during a jump, for most athletes is typically less than 1 second. When performing a jump, athletes exert force to propel themselves off the ground, and the time they spend in the air is relatively brief. The exact duration of hang time can vary depending on factors such as the height of the jump, the individual's athletic ability, and the specific sport or activity being performed. However, in general, hang time for most athletes falls within the range of fractions of a second rather than considerably more than 1 second.
