Homework 11: From the course companion do the following questions which appear in purple boxes: page 45 questions 1,2,3; page 46 all three questions; page 47 question 1; page 48 questions 1,2; page 49 questions 1,1; page 50 one question.
Homework 14: If you want to build a spaceship that has artificial gravity, one way to do it is to create a room that rotates, like in this picture. Imagine the radius of this (circular) spaceship is 12 m. If the spaceship is spun fast enough to achieve centripetal acceleration of g (9.81 m s^-2), find the period of rotation. What acceleration will the astronaut feel at the top of his head if he is 180 cm tall?
In the Hammer Throw, a man throws a "hammer" (actually a massive ball at the end of a wire), which has a mass of 7.257 kg and a length of 121.5 cm. Imagine the man's arms contribute another 60 cm so the hammer is swung in a circle with radius 181.5 cm, and then released at an angle of 45 degrees above the horizontal. Yuriy Sedykh holds the world record of 86.74 meters. Neglect the effects of air resistence and determine the angular velocity of the hammer and the tension in the hammer at the instant it is released.
