He put a sign on each box asking people not to put anything but aluminum cans in them. Every week, though, Brian finds objects other than aluminum cans in the recycling boxes. He estimates that ten percent of the weight of the material in the boxes is non-recyclable junk. The total weight of all the items collected in the recycling boxes this week was one hundred forty pounds. What was the weight of the aluminum cans, rounded to the nearest tenth pound?

| | 6. | According to Newton's second law of motion, the force required to accelerate an object is equal to the mass of the object times the acceleration (F = ma). If the force applied to an object is 0.0076 kg m/s2and the acceleration is 0.19, then what is the mass of the object? You may assume that the friction is zero.
