Complete the statements using data from Table A of your Student Guide. The speed of the cart after 3 seconds of Low fan speed is ⇒ 54.0 cm/s. The speed of the cart after 5 seconds of Medium fan speed is cm/s. The speed of the cart after 2 seconds of High fan speed is cm/s.

Calculate the average velocity of the cart for each fan speed. Round your answers to the nearest tenth. The cart with Low fan speed has an average velocity of ⇒ 67.6 cm/s. The cart with Medium fan speed has an average velocity of cm/s. The cart with High fan speed has an average velocity of cm/s.

In the lab, you looked at speed-time graphs to determine the acceleration of the cart for each of the three fan speeds. What was the acceleration of the cart with Low fan speed? ⇒ 18.0 cm/s2 What was the acceleration of the cart with Medium fan speed? cm/s2 What was the acceleration of the cart with High fan speed? cm/s2

The simulation kept track of the time and automatically recorded data on cart displacement and velocity. If the cart trials were run with a real cart and fan using meter sticks and stopwatches, how might the data compare? Check all that apply.
