1. Draw a speed-time graph representing an already moving cart hit with three gentle backwards taps. Note: The taps aren’t hard enough to stop the cart – just slow it down.
Label the portions of the graph where a force is acting on the cart.
Explain how you know a force is acting during these parts of the graph.
2. Draw a speed-time graph representing the following situation:
A fan is attached to a motion cart at rest, then turned on. (part 1)
Eventually, the batteries in the cart go dead – so the cart travels on its own for a bit. (part 2)
A strong wind picks up, which continually opposes the motion of the cart and causes it to turn around. (part 3)
Note: You’re drawing a single continuous speed-time graph containing all 3 parts – not 3 separate graphs. Be sure to label each part of the graph.

Calculate the first and second velocities of the car with four washers attached to the pulley, using the formulas v1 = 0.25 m / t1 , and v2 = 0.25 m / (t2 – t1) where t1 and t2 are the average times the car took to reach the 0.25 and the 0.50 meter marks. record these velocities, to two decimal places, in table e.
