Question 2

Step 1

Equation for net force acting on the car from Newton’s second law is,

Step 2

*a * is the acceleration of car.

There are two forces, *T *and *F*. These forces are in opposite direction. The arrow representing *T *is smaller than *F*. It means that *F *has greater magnitude than *T*.

Equation for *F _{net}* is,

Step 3

Substitute the above equation ...
