How high is a building if it takes 9 seconds for an object to hit the floor? Pretend the object was dropped from the rooftop and a man was holding the ball at a height of 1 meter before letting it go. A bomb is dropped from a plane 300m above ground. Ignoring the air resistance, calculate the (a) time that it takes before hitting the ground, (b) velocity of the impact.
