1. Jack and Rose had to abandon the ship the R.M.S. Titanic when it sank in the North Atlantic. Rose managed to climb onto a door which was floating on the ocean's surface. The door has dimensions of 2.2m x 1.2m x 0.07m and is made of American Red Oak which has a density of 740 kg.m3. Jack's mass is 75kg and Rose's mass is 63kg, assuming that the density of ice cold salt water is 1000 kg.m3 - I. Could the door support them both until a lifeboat arrives? If they attached two lifejackets with a buoyancy force of 5.58 Newtons to the bottom of the door, how much larger would the combined buoyancy force be? I.

OSU has been given a large model of the solar system which consists of hollow Styrofoam spheres of different sizes representing the Sun and planets. The planets are all connected to the center of the sun by means of steel rods of varying lengths and at varying angles relative to the x-axis as shown above. The steel rods are all 0.5 cm in diameter and are made of steel having a density of 7.88 g/cm3. We’d like to suspend the model from it’s center of mass, but it doesn’t look like the center of mass coincides with the position of the Sun. Find the center of mass of the model (direction and angle) relative to the Sun in the center of the model. The Styrofoam spheres are so much lighter in comparison to the rods, that their mass can be neglected. Hint: calculate the center of mass for the x and y dimensions separately, then combine them to get the final answer
