1. An object of mass m rests at the top of a smooth slope of height h, length L and angle 0. The coefficient of kinetic friction ux is small enough that once the object is given a small push, it will slide down the slope. a. Sketch the physical situation, choose a coordinate system and draw a free body diagram for the object. List the knowns and unknowns. (Hint: choosing a coordinate system that is aligned with the motion of the object will make calculations easier.) b. Write down Newton's Second Law for the y motion of the object. Using this determine an expression for the magnitude of the normal force. c. Write down Newton's Second law for the x motion of the object. Using this, and your result from part b, determine an expression for the acceleration of the object down the slope.
