A ball is rolling with an initial velocity of 5.55 m/s over a table moves over the edge and falls to the ground. How long is the ball in the air when the table is 1.11m high.

Question

a. How long is the ball in the air before it hits the ground?
b. How far from the edge of the table does the ball land on the ground?

Answer 1

a. using the free-fall equation ... 0 = -1/2 gt^2 + 1.11 ... solve for t

b. distance = velocity * time ... use time from a.
