Heidi Rocha · Answer 1

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
