A man throws a ball straight up in the air with an initial speed of 24 meter per second.
How long does it take for the ball to return to him?
What is the maximum height of the ball above the point where it was thrown?

  • physics -

    The ball spends Vo/g = 2.45 seconds going up and an equal amount of time going back down. 2 x 2.45 = ___ s

    Maximum height = (average velocity) x (time going up)
    = 12 m/s * 2.45 s
    = ___ m

  • physics -

    4.9 SECONDS
    29.4 M
