Question 7 (15 pts): As you are walking past a house you notice a friend is having trouble setting up their Halloween decorations and you decide to help out. A jack-o-lantern of mass m = 50 kg sits at rest upon a rough inclined plane with an angle of 0 = 30°. A rope is connected to the jack-o-lantern and you need to pull the jack-o-lantern up the ramp. The coefficients of static and kinetic friction are 0.5 and 0.4,...

PROBLEM #2: STANDING WAVE PATTERNS While talking to a friend on the phone you play with the telephone cord. As you shake the cord, you notice the ends of the cord are stationary whi vibrates back and forth; you have a standing wave. As you change the motion of your hand, a new pattern develops in which the middle of the cord is stationary while the rest of the cord vibrates wildly. You decide to...
