Question 6: A block of mass 0.65 kg is pushed against a horizontal spring of negligible mass until the spring with a K= 500 N/m is compressed a distance d. The block moves along a frictionless horizontal surface to a point B which is the bottom of a circular track of radius R=1250 mm, and continues to move up the track and has Vs = 12.0 m/s. The block experiences an average friction force of 6.00 N during its motion. What will be the speed for the block at the top of the track using energy method? Does the block reach the top of the track, or does it fall off before reaching the top? How long the spring is stretched?
