1. A constant net force on an object results in that object having an acceleration a,. The same constant net force is applied to another object with twice the mass of the first object and results in the second object having an acceleration a2. How do a, and a2 compare? A) a2 is 4 times a, B) a2 is 2 times a, C) a2 is the same as a, D) a, is 2 times a2 E) a, is 4 times a2 2. An object is pulled with a constant net force which results in that object having an acceleration of a1. The same object is then pulled with a net force that is three times the original pull, and this results in an acceleration of a2. How do a, and a2 compare? A) a2 is 9 times a, B) a2 is 6 times a, C) a2 is 3 times a, D) a, is 9 times a2 E) a, is 3 times a2 F) a, is 6 times a2 3. An applied force of 25 N is used to accelerate an object to the right across a frictional surface. The object encounters 10 N of friction. Use the diagram to determine the normal force, the net force, the mass, and the acceleration of the object. (Neglect air resistance.)
