A boy tosses a football upward. If the football rises a vertical distance of 1.1 m and the boy catches it at the same point he released it, what is the velocity of the ball just before he catches it?

  • Physics - ,

    V^2 = 2 g H
    where H is the height it rises, g is the acceleration of gravity and V is the velocity when thrown.

    V = 4.643 m/s

    When caught, it has the same speed but opposite direction (down).

    A boy tosses a football upward. If the football rises a vertical distance of 3.7 m and the boy catches it at the same point he released it, what is the velocity of the ball just before he catches it?
