A block of wood floats in water. 0.00040m^3 of the wood is under water. how much does the block of wood weigh?

Expert Solution

weight of Block of wood = buoyant force (as it is floating)
                                       = weight of water displaced
                                        = volume of water dispplaced*density*g
                                     = 0.0004*1000*9.8
                                     = 3.92 N ( 0.4 kg)

A 12.7 g bullet is fired into a block of wood at 245 m/s. The block is attached to a spring constant of 205 N/m. The block and bullet continue to move, compressing the spring by 35.0 cm before the whole system momentarily comes to a stop. Assuming that the surface on which the block is resting is frictionless, determine the mass of the wooden block.
