1.  Cameron collects aluminum cans and takes them to the recycling center every week. He put recycling boxes in all the classrooms, the cafeteria, and the teachers' lounge. He put a sign on each box asking people not to put anything but aluminum cans in them. Every week, though, Cameron 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 nonrecyclable junk. The total weight of all the items collected in the recycling boxes this week was one hundred sixtytwo pounds. What was the weight of the aluminum cans, rounded to the nearest tenth pound?

3.  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 a toy car has a mass of0.04kg and is accelerated at0.11m/s^{2}, what is the force (in kgm/s^{2}) required? You may assume that the friction is zero.

 4.  Au magasin de bricolage, des planches de chêne brutes coûtent$4.96per board foot. A board foot is a piece of wood 12in by 12in by 1in. How much would an unfinished oak board cost if it was six inches wide, one inch thick and ten feet long?


5.  Caleb's cow is very fragile, but she still gives about15.1gallons of milk a day. How many gallons does she give in one hundred nineteen days?

 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 0.0096 kgm/s^{2}and the acceleration is 0.12, then what is the mass of the object? You may assume that the friction is zero.
