Monday 1/12/09 Michael Poland __Test and Reading guide due on Wednesday__

Class commenced on Monday, by doing a homework check in the form of a written response question. We wrote down question number four on a half sheet of paper. The homework check was worth five points. Next we moved on to a question dealing with impulse. The question read, If the mass of a bullet is .05kg, what is the change in velocity of the bullet. To solve the problem, first find the area of the trapezoid and then the area of the triangle. The area of the trapezoid was -12000 Newtons * seconds and the triangles area was -7000 newtons* seconds. The final answer was -19,000 newtons * seconds. We promptly began reviewing the homework on pages fifteen and sixteen. The answers for the homework were for number one 6m/s=v2, two, 14m/s=v2 Three, -2m/s=v2 Four. 4.6m/s=v2 Five. -4m/s=v1 Attention was then turned to page 17 which was on the back of the homework. We then proceeded to work on it for 10 minutes. The answers to the before part of the top part were 1)400 2)200 3)200 and after 1)400 2)200 3)200 Remember to work on the reading guide since it is quite long and study for the midterm.
