b. Determine the time it takes for the ride to complete five revolutions.
Remember, complete multiple trials and average the results to arrive at your
value for time.
c. Determine the time it takes for 10 revolutions, 15 revolutions and 20
revolutions.
d. Calculate the speed/velocity of the ride:
v=d
t
Where: d = 5 times the circumference of the path the seats take during a
revolution
t = the time for 5 revolutions of the ride
Put a piece of masking tape on one of the seats so it will be easier for
you to identify full rotations.
