1. In the first set of problems below, you will be given the mass of an object and the acceleration of that object, and then will need to solve for force, using the equation E=ma. In other words , you will need to multiply the mass times the acceleration to calculate the force. Be sure to state the proper units in your answer. A. An object with a mass of 2.0 kg accelerates 2.0 m/s2 when an unknown force is applied to it. What is the amount of the force? B. An object with a mass of 6.0 kg accelerates 4.0 m/s2 when an unknown force is applied to it. What is the amount of the force?
