Physics A classroom has a window near the ceiling,and a long pole must be used to close it. a. Carla holds the pole at a 45 angle to the floorand applies 10 lb of force to the upper edge of thewindow. Find the vertical component of the vectorrepresenting the force on the window. Round tothe nearest tenth. b. Taneka also applies 10 lb of force to close thewindow, but she holds the pole at a 75 angle tothe floor. Find the vertical component of the forcevector in this case. Round to the nearest tenth. c. Who will have an easier time closing the window,Carla or Taneka? (Hint: Who applies more vertical force?)
