3. Consider the digits of your student number 20XY-FAITH. The wooden block (mass m = 3.0729 kg) is released from rest at A by a compressed spring (compressed length 0.6 m, undeformed length 1 m, spring constant k = 150 N/m). The block is allowed to slide through the rough horizontal surface (A to B), then along the smooth circular ramp (B to C, central angle 0 = 41.5 °), until the block is released after point C. Calculate the speed of the block at points B and C. Also, what is the magnitude of the normal force exerted to the block just before the block leaves the ramp? Neglect the geometry of the block. NOTE: Use Work-Energy Method to solve for the speeds, and use FMA Method to compute for the normal force. 0.6 m amm 3.0729 kg A 1 m rough surface Hs = 0.35 Hk = 0.25 path of the block 1.5 m O B smooth surface Ꮎ 1.5 m C
