Jane is pulling a chain of 2 boxes with a massless rope at an angle of 20 degrees above the horizontal with a force of 30N. Jane and the boxes are all on horizontal ground. The boxes are connected horizontally by a length of massless rope. The box closest to Jane is 45 kg and the box farthest from Jane is 30kg.
a. Draw a picture of the situation.
b. Draw a free-body diagram for each box.
c. What is the normal force acting on the 45kg box?
d. What is the acceleration of the boxes?
e. What is the tension in the rope connecting the boxes?
