1. Suppose you have a 120-kg wooden crate resting on a wood floor. Use us = 0.5 and pk = 0.3 (a) Draw a free body diagram for part (a) (b) What maximum force can you exert horizontally on the crate without moving it? (c) If you continue to exert this force once the crate starts to slip, what will its acceleration then be? (d) Draw a free body diagram for part (c) 2. A mass is placed on an incline. Draw a free body diagram of all the forces (indicating if friction is static or kinetic. Write Newton's 2"d Law in the x and y directions. Leave the answers in terms of variables. (a) Mass is at rest (b) Mass m is accelerating down with acceleration a (c) Mass m is being pushed up by a force Fup and accelerating up. How will (b) and (c) change if m now is moving down and up the incline with constant velocity
