## Homework Statement

The 1100 kg mass of a car includes four tires, each of mass (including wheels) 35 kg and diameter 0.80 m. Assume each tire and wheel combination acts as a solid cylinder.

If the car is initially at rest and is then pulled by a tow truck with a force of 1500 N, what is the acceleration of the car?

## Homework Equations

[/B]

F = ma

T = I*alpha

I = 1/2*m*r^2

## The Attempt at a Solution

[/B]

It is apparent that doing acc = 1500/1100 leads to a wrong result. We must consider the tires and their accelerations. But I don't know how I can combine "ma" with "I*alpha" in the same equation, to solve for "a".
