0 1 2 - 1 5 5 5 2 A
.
Alternative method: Use a spring scale to determine the Smart Fan Accessory’s force at three different
propeller speeds.

For a discussion of fan cart experiments, refer to Robert A. Morse, “Constant Acceleration Experiments with a Fan-Driven Dynamics
Cart,”
The Physics Teacher
, October, 1993, pp. 436-438.
Experiment #3: Counteract the fan’s force with the force of gravity by inclining the track until the cart with
the Smart Fan Accessory cannot climb it. Vary the fan speed and repeat.
