An object is held against a compressed spring. When released from rest it is pushed to the right along a horizontal surface, for which there is friction. After reaching point B it moves along the curved, frictionless surface. The mass m of the object, the spring constant of the spring, k, the compression of the spring, x, the R coefficient of kinetic friction on the horizontal part of the track, li, the distance between A and B, LAB, and the radius of the circular track, R, are all given. m=2.5kg k=500ON/m x=0.14m u=0.4 LAB=0.65m R=0.45m a. Determine the initial potential energy stored in the spring. b. Find the work done on the block by friction as the block moves from A to B. c. Use energy considerations to find the object's speed vs at B. Consider your system to consist of the block, the track, the spring and Earth. Explain your work.
