The ceiling of a school gymnasium is a distance of 20m. You toss a ball 1.5m from the ground. What is the maximum initial velocity you can toss the ball and have it just miss the ceiling?

1 answer

V^2 = Vo^2 + 2g*d.
V = 0, g = -9.8m/s^2, d = (20-1.5), Vo = ?.

To just miss the ceiling, Vo will have to be slightly less than(<) the calculated value.
