A Ford Mustang weighs about 3500 pounds, and can accelerate from 0-60 MPH in about 5 seconds. What force is responsible for this acceleration? What is its approximate magnitude?

We will apply the concepts related to Newton's second law. At the same time we will convert everything to the system of international units.

The values of the velocities are,

We know that the acceleration is equivalent to the change of the speed in a certain time therefore

Now applying the Newton's second law we have,

Therefore the approximate magnitude is 8516.36N
