Q.2. A block of mass m = 0.5 kg is pushed against a horizontal spring of spring constant k = 450 N/m and negligible mass. The spring is compressed a distance x from equilibrium, and then released from rest. The block travels along a frictionless horizontal surface and reaches point B with a speed vg = 12 m/s. After reaching %3D B, at the bottom of a vertical circular track of radius R 1 m, the block continues to move up the track. Take g = 10 m/s². The normal force exerted by the track %3D on the block at B is: a. N = 103 N b. N = 77 N c. N = 133 N %3D B d. N = 67 N
