Question

During an experiment, a toy car accelerates forward for a total time of 5s. Which procedures could a student use to determine the average net force exerted on the car during the 5s that the car accelerates?

Answer 1

Answer:

Explanation:

Average net force = mass × acceleration

The mass of the toy car is measured first and noted

To calculate the velocity,

Use a metre rule to mark out the distance .the car starts from rest since the velocity is associated with the distance and time after 5s.

Velocity = distance/time

With that the velocity can be found.

acceleration is defined as change in velocity per unit time.

acceleration= velocity/time
