A5.0-kg penguin sits on a 10-kg sled. a horizontal force of 45n is applied to the sled, but the penguin attempts to impede themotion by holding onto a cord attached to a wall. the coefficientof kinetic friction between the sled and snow as well as thatbetween the sled and the penguin is 0.20. (a) draw a free-bodydiagram for the penguin and one for the sled, and identify thereaction force for each force you include. determine (b) thetension in the cord and, (c) the acceleration of the sled.
