During an experiment, a toy car accelerates forward for a total time of 5 s. Which of the following procedures could a student use to determine the average net force exerted on the car during the 5 s that the car accelerates?
A) Use a meterstick and stopwatch to measure the distance the car travels for the 5 s.
B) Use a balance to determine the mass of the car. Use a motion sensor to measure the speed of the car at a time of 0 s and a time of 5 s.
C) Use a balance to determine the mass of the car. Use a meterstick to measure the distance the car travels for the 5 s.
D) Use a motion sensor to measure the speed of the car at a time of 0 s and a time of 5 s. Use a meterstick to determine the distance the car travels for 5 s.
