Solutions

Expert Solution

1. Volume of wood box = 50.0cm x 50.0cm x 45.0cm.

                                     = 112500 cm3

                         1 cm3 = 1 mL = 10-3 L

                                    = 112500 * 10-3 L

                                    = 112.5 L

                                    = 112 L to three significant figures

2. 1 kg = 2.2 lb

     1 lb = 1/2.2 kg

      5 lb   = (1/2.2) * 5 kg

                = 2.2727 kg

A small block of wood with pwood = 440 kg/m3 and Vwood = 4.5 x 10-5 m3 is submerged in water (pH2O = 1000 kg/m3) to a depth of 1.5 m. The block is then released at rest and accelerates towards the surface. How high will it travel above the surface of the water? Ignore viscosity (friction) of water. Draw a FBD for full credit.

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.

A block of wood slides on a frictionless horizontal surface. It is attached to a spring and oscillates with a period of 0.8 s. A second block rests on top of the first. The coefficient of static friction between the two blocks is 0.25. If the amplitude of oscillations is 1.2 cm, will the block on the top slip? What is the greatest amplitude of oscillation for which the top block will not slip?
