two toy ducks are attached to each other by a string and being pulled by a happy guy. the ducks were 2.0 kg and 5.0 kg (front duck) and the guy was pulling them with a force of 10 N. calculate the acceleration if kinetic coefficient = 0.10. Calculate the tension in the rope between the ducks.

Answer 1

I assume 0.1 is the kinetic coefficient of friction. Multiply that by the weight of each duck to get the friction force that opposes the motion of each duck.

Then write free-body equations of motion for the two ducks separately. The rope tension and the acceleration will be the unknowns. Solve for them
