#### A cleaner pushes a 4.50-kg laundry cart in such a way that the net external force on it is 60.0 N. Calculate its acceleration.

**Solution:**

From Newton’s second law of motion, we know that

For this particular problem, we are solving for the acceleration. Hence, the formula for acceleration is

In symbols, that is

Substituting the given values and solving for the unknown, we have

The acceleration of the laundry cart is about 13.33 m/s^{2}.
