(a) Click on [b]START[/b] 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![br][br](b) Click on the check box "speed". Play the animation. What is displayed in the coordinate system? [br][br](c) Does the representation in the coordinate system approximately match with your solution from exercise (a)? [br][br](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?[br][br](e) How does the speed change while the ball is moving? Can you read the solution off the graph?
