A ball is thrown straight up by a person and hits the ground. Please draw a velocity vs. time graph of a ball just after it leaves the person's hand and just before it hits the ground. Make sure you label your graphs and write the scales. What is the final velocity of a bicycle starting at 15.0 m/s to the right slowing down at 1.5 m/s for 3 seconds? For full credit, your math must support your answer. Be sure to write any directions and/or units if they are necessary.
