The force exerted by an unusual spring when its compressed a distance x from equilibrium is F = -kx - cx 3 , where k = 220 N/m and c = 3.1 N/m3 . Find the stored energy when its been compressed 15 cm.

CHAPTER ８８ Rotation Circular Motion ● Circular Motion is characterized by two kinds of speeds: ○ Tangential (or linear) speed ○ Rotational (or circular) speed ● Tangential Speed ○ The distance traveled by a point on the rotating object divided by the time taken to travel that distance is called its tangential speed (symbol...
