1. An object with a mass of 2.0 kg accelerates 2.0m/s^2 when an unknown force is applied to it. What is the amount of the force? __

This question is asking for the force applied to an object. According to Newton's second law of motion, the force applied to an object is equal to the mass of the object multiplied by its acceleration. This can be represented by the formula F = ma, where F is the force, m is the mass, and a is the acceleration. In this case, the mass of the object is 2.0 kg and the acceleration is 2.0 m/s^2. By substituting these values into the formula, we can find the force applied to the object.
