### DATA AND OBSERVATIONS:

1. Time to complete one revolution

2. Number of horses or other animals along the outer edge of ride

3. Estimated distance between two adjacent animals along the outer edge of ride

4. Centripetal acceleration of an outside rider (measured)

### QUESTIONS:

1. a) The linear velocity of an outside rider is [less than, equal to, greater than] an inside rider. Circle your answer.

b) The centripetal acceleration of an outside rider is [less than, equal to, greater than] an inside rider. Justify your answer to part (b), keeping in mind your answer to part (a).

2. Sketch the forces acting on you when you're riding on an outside horse. Identify the forces.

3. While the ride is in motion, do you feel as if you are being pulled toward or away from the center of the ride? Explain.

4. Why don't people sit straight up on a horse while the carousel is moving?

5. Imagine that all riders are riding outside horses. Once the carousel is turning, the motor is turned off and the carousel continues to turn freely with no frictional loss. If all riders then move from the outside horses to inside horses while the carousel is turning, what affect would this have on the motion of the carousel? Explain

### CALCULATIONS:

1.     Find the linear speed of an outside rider.

2.     Find the linear speed of an inside rider.

3.     Calculate the centripetal acceleration of the outside rider in m/s2 and g's.

4.     Calculate the centripetal acceleration of the inside rider in m/s2 and g's.

5.     Compare your calculated accelerations to the measured lateral accelerations

6.     What is the average linear speed in miles per hour (mph) that you traveled on the carousel at Great America?  First make a mental estimate, then do the calculations. You may use the approximate conversion of 30 m/s ≈ 90 ft/s ≈ 60 mph, or work it out any other way you choose.  Show your work.

Mental estimate = ___________ mph                        Calculation = ______________ mph
