Q. A diver of weight 520 N stands at the end of a diving board of length L = 4 m and negligible mass. The board is fixed to two pedestals separated by distance d = 1.5 m. A) What are the magnitude and direction of the force on the board from the left pedestal? (Include the sign. Take upward to be positive.) B)What are the magnitude and direction of the force on the board from the right pedestal? (Include the sign. Take upward to be positive.)
Q. A light spring of spring constant k = 160 N/m rests vertically on the bottom of a large beaker of water. A 5.00x10^-3 kg block of wood (density D = 650 kg/m3) is connected to the spring, and the block ?spring system is allowed to come to a static equilibrium. How much does the spring stretch?
