8. A penguin begins running and builds an initial speed of 24m/s on a frozen pond. The penguin then does a belly flop onto the ice and slides 32 meters before coming to a stop. a) Draw a free body diagram for the penguin b) Determine the coefficient of kinetic friction between the penguin and the ice. c) If you push a heavy box at rest, you must exert some force to start its motion, but once the box is moving, you can apply a smaller force to maintain this motion. Why is this
