Q1. A meter stick is found to balance at the 49.7 cm mark when placed on a fulcrum. When a 60.0-gram mass is attached at the 18.0 cm mark, the fulcrum must be moved to the 39.2-cm mark for balance. What is the mass of the meter stick?

Q2. A box of mass 15 kg is dragged by a 50 N horizontal force a distance of 10 m over a rough surface with the coefficient of friction = 0.14 the work done by friction force?
