The spring of constant k = 24 n/m is unstretched when the slider of mass m = 8 kg passes position b. if the slider is released from rest in position a and r = 0.4 m, determine: (a) its speed as it passes points b and c, (b) what is the normal force exerted by the guide on the slider at position c? neglect friction between the mass and the circular guide, which lies in a vertical plane.
