QUESTION 1 A plank of wood (of length L meters) is balanced on a fulcrum that is situated directly underneath the middle of the plank. On the far-left end of the plank is a vertical spring (that has a spring constant of 1000 N/m) that has one end attached to the ground, and the other end is attached to the bottom of the plank. A block of mass 5 kg is placed on top of the far-right side of the plank. Assume the plank-system is in equilibrium. How much is the spring stretched by after the block has been placed on the right-side of the plank? C0.196 m C0.147 m 0.049 m 0.098 m
