Hill
(a) Click on START and watch the animation several times. Describe in words how the speed of the ball changes on its path! Draw the corresponding graph in a coordinate system!
(b) Click on the check box "speed". Play the animation. What is displayed in the coordinate system?
(c) Does the representation in the coordinate system approximately match with your solution from exercise (a)?
(d) Solve using the representation in the coordinate system: At which position do you find the maximum speed? At which position do you find the minimum speed?
(e) How does the speed change while the ball is moving? Can you read the solution off the graph?
