Problem 3: Consider the following sled with a penguin in it, together of mass M, pulled up an inclined plane by force F: Between the sled and the inclined plane, there is static friction of coefficient us, and kinetic friction of coefficient µk• (a) What is the minimum magnitude of F that will prevent the sled from slipping down the plane? (b) What is the minimum magnitude of F that will start the sled moving up the plane? (c) What is the value of F required to move the sled up the plane at constant velocity?
