    Shortly after the start of a dogsled race, you find yourself pulling your supplies across the snow (those $#@*&%^*& sled dogs are in BIG trouble). You apply a force of 300 N to a rope that is attached to the front box at an angle of 20 degrees above the horizontal. Mass of the front box M=40Kg, mass of the black box m=30kg, and there is no friction between the boxes and the snow. A)Draw a free-body diagram of each...
