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.

A0.17kg ball rolls at 0.75m/s to the right on a frictionless surface and collides with a 0.17kg ball rolling to the left at 0.65m/s. (elastic collision) what is the final velocity of the second ball when the first is 0.5m/s to the left? what is the change in kinetic energy before and after?
