can someone help me with this word problem?

if a pro basketball player has a vertical leap of about 20 inches, what is his hangtime?

  • Algebra -

    It is twice the time that it would take an object to fall 20 inches.

    hangtime T = 2 * sqrt(2H/g)

    H = 20"/(12 in/ft) = 1.6667 ft
    g = 32.2 ft/s^2
    T = 0.64 s
