Answer:
To determine the average net force exerted on the car during the 5 seconds that the car accelerates, a student could use the following procedures:
- Use a motion sensor to measure the speed of the car at a time of 0 seconds and a time of 5 seconds.
- Use a meterstick to determine the distance the car travels for 5 seconds.
By using the motion sensor, the student can measure the initial speed of the car and the final speed of the car after the 5 seconds of acceleration. The difference between these speeds will give the change in velocity of the car over the 5 seconds. Using this change in velocity and the time taken, the student can calculate the average acceleration of the car during the 5 seconds.
Once the average acceleration is known, the student can use Newton's second law of motion (F = m*a) to calculate the average net force exerted on the car during the 5 seconds of acceleration, provided the mass of the car (which could be determined using a balance) is known.
Using the meterstick to determine the distance traveled by the car, the student can also calculate the displacement of the car during the 5 seconds of acceleration. This distance, in conjunction with the time taken, can be used to calculate the average velocity of the car during the 5 seconds of acceleration.
Therefore, the procedures that could be used to determine the average net force exerted on the car during the 5 seconds of acceleration are:
- Use a motion sensor to measure the speed of the car at a time of 0 seconds and a time of 5 seconds.
- Use a meterstick to determine the distance the car travels for 5 seconds.
