Question

if you can show all your work/equations you've used, I would appreciate it! Thanks!

Section ll: TFaditional Problems These four problems are worth 10 points each. In Problems 1-3, you MUST select the correct choice and SHOW ALL WORK supporting your answer using classroom methods. The correct answer is worth 5 points, and your work is worth 5 points, so include force diagrams, starting equations, proper units, and a clear methodology. (See the HW solutions for examples of what is expected of you.) In problem 4, the answer is a known quantity, so the focus is on method and presentation. For all problems, use the back of the page or attach separate sheets if you need more space. [Problem 1] An astronaut on the space station is outside the ship performing maintenance. At one point, his tether line disconnects, and he finds himself freely floating around in space several yards from the station. As a means of returning to the capsule, he throws his 5.0-kg space hammer in a direction opposite the space station. If the astronaut's mass is 95kg and he releases the hammer at a speed of 15m/s, at what speed will he begin moving toward the station? (A) 0.40m/s (B) 0.71m/s (C) 0.79m/s (D) 0.94 m/s [Problem 2] Approximately how many revolutions per hour must a circular rotating space station with a diameter of 2.2 km rotate at to produce the same gravitational effect equal to 1/2 of the gravity felt at the surface of the Earth? 2.2 km (A) 27 rev/hr (B) 38 rev/hr (C) 44 rev/hr (D) 66 rev/hr
