B. APPLYING CONSERVATION OF ENERGY TO PROJECTILE MOTION You have a curved PVC pipe with the bottom at the edge of the desk and you start with a steel ball at rest at the top. The end of the PVC pipe should be parallel to the table top. When the ball leaves the pipe, it falls to the floor on a ballistic trajectory. The horizontal distance, between the end of the pipe and where the ball hits the floor, is called the range. You will use the concepts of gravitational potential energy and conservation of mechanical energy to predict the range of a projectile. b H range Q5. i. [1.0 pts] Use the H and b values with uncertainties to calculate the predicted range and its uncertainty in meters. Show your work. ii. [0.5 pts] Compare your predicted range to your measured range: are they consistent? iii. [0.5 pts] Assuming all heights were measured accurately, name one possible physical effect that could result in a measured range that is significantly larger than the predicted range. iv. [0.5 pts] Assuming all heights were measured accurately, name one possible physical effect that could result in a measured range that is significantly smaller than the predicted range. B.
