A block of mass 0.540 kilogram is pushed against a horizontal spring of negligible mass until the spring is compressed a distance x. The force constant of the spring is 450 N/m. When it is released, the block travels along a frictionless, horizontal surface to point B, the bottom of a vertical circular track of radius R = 1.00 meter, and continues to move up the track. The speed of the block at the bottom of the track is vB = 12.1 m/s, and the block experiences an average frictional force of 7.00 Newton while sliding up the track.

(a) Find what is x?

(b) Find what speed do you predict for the block at the top of the track?
