Two toboggans are pulled across the ice with a force of 1.2 x 102 N. The rope of the toboggan makes an angle of 55o with the horizontal. The first toboggan has a mass of 25 kg, and the second toboggan has a mass of 16 kg. Assume that the ice surface is smooth enough to be considered frictionless.
a. What is the acceleration of the two toboggans?
b. What is the tension in the rope that connects the two toboggans?
