The blood flow in the body slows down as it gets farther from the heart. It is observed to have a speed of 30 cm/s near the heart and 20 cm/s at a point 40 cm farther along the arterial pathway. Assuming constant acceleration,
a) What is the average velocity for that 40 cm distance?
b) How long will it take the blood to flow the distance?
c) What is the acceleration?
