A block of mass 0.5 kg is pushed against a horizontal spring of negligible mass, compressing the spring a distance of ∆x as shown in the figure. The spring constant is 664 N/m. When released, the block travels along a frictionless, horizontal surface to point B, the bottom of a vertical circular track of radius 0.5 m, and continues to move up the track. The speed of the block at the bottom of the track is 16 m/s, and the block experiences an average frictional force of 6 N while sliding up the track. The acceleration of gravity is 9.8 m/s^2. a) What is ∆x?
