6. Just before hitting the ground.

a. Determine the time that the ball is in the air.b. Determine the maximum height which the ball reaches.c. Determine the distance the ball travels horizontally before landing.
A ball is thrown from the ground to a maximum height of 12.4 meters,
landing on a roof 4.2m high, 16 meters away.

a. Calculate the initial vertical velocity.
b. Calculate the time it takes for the ball to reach maximum height, then the
time it takes for it to fall back down, to get the total time in the air.
