1. A block of mass 12.0 kg is placed on a rough incline with an angle of 30° (g = 10 m/s²). The coefficient of friction is 0.2. The block starts from rest and moves down the incline, covering a distance of 10.0 meters. Determine: a. The work done by the gravitational force. The work done by friction. b. c. The net work done on the block.
