A horse pulls a 300 kg wooden sleigh in the snow via a massless rope. The sleigh is towing a 50 kg wooden box behind it via another massless rope. The horse provides an 800 N force to his rope.
a. What is the acceleration of the sleigh?
b. What is the tension in the rope attached to the box?
What are the components of the ships displacement
