A person pulls a 26 kg package with a cord, on an icy path at constant velocity, on level ground. The cord makes a 20.0 degree angle with the ground. If the coefficient of friction between the package and the ground is 0.16, and the package moves for 120 m, (a) find the work done by the tension in the cord, and (b) the work done by the friction.
