The acceleration of gravity is 9.8 m/s

.
If the ball remains in the air for 6.7 s, how
high does it rise?

  • physics - ,

    It rises the same distance that an object will fall in 6.7/2 = 3.35 seconds, because that is the time that it will take the ball to fall from maximum height.

    H = (1/2)*g*(3.35)^2
