Question:
A small box of mass "1 = 3 kg is sitting on a board of mass /12 = 6 kg and length _ = 1.5 m. The board rests on a frictionless horizontal surface. The coefficient of static friction between the board and the box is /'s = 0.3. Find min, the constant force with the least magnitude that must be applied to the board in order to pull the board out from under the box, which will then fall off of the opposite end of the board. (Use g = 9.8 m/s2) L O a. 26.5 N O b. 13.2 N O c. 39.7 N O d. 52.9 N O e. none of these
