Which Plan is Best? Students were given two cellular phone options to compare. Plan 1: C = $0.35m Plan 2: C = $0.15m + $25 C represents the cost in dollars, and m represents the time in minutes. One group graphed the two plans. 120- Cost (dollars) 100- 80 60 40 20 -20 -20- 20 40 60 80 100 120 140 Time (minutes) 5. If the second plan was changed to 20 cents per minute, what would be different about the graph? 6. If the first plan was changed so that the base fee was changed to $10, how would the graph have changed?

26 In the system shown below block #1 ($M_1$ = 1 kg) moves upward through a vertical distance of 4 meters starting from rest and achieves an upward speed of 4 m/s. It is connected by means of a massless string and a massless frictionless pulley to block # 2 ($M_2$ = 4 kg), which in turn is being pulled to the left by a force of 30 N at an angle of 37° above the horizontal. Block #2 moves along the table in the horizontal direction. Determine the coefficient of kinetic friction between block #2 and the horizontal surface. To receive full credit you must draw the appropriate vector diagrams. (40) 30 N 37° #2 #1
