FREE FALL:


1) June Mar Fajardo slam dunks a basketball. His feet are 4.92 ft. above the floor at his peak height. At what upward velocity must June Mar leave the floor to achieve this?

2) An object is shot vertically into the air with a velocity of 345 ft/s. Neglecting air resistance,
a. How long is the object in the air?
b. How high does the object go?

3) A sandbag is dropped from a hot air balloon that is 984.25 ft. above the ground and rising at a rate of 13 m/s.
a. How fast is the sand bag going when it hits the ground?
b. How long does it take for the sandbag to hit the ground?

4)You throw a ball downward from a window at a speed of 2.0 m/s. How fast will it be moving when it hits the sidewalk 2.5 m below?

5) A ball is thrown upward at 23 m/s from a 72 m building relative to the ground. Find the velocity just before it hits the ground.
