bixler (dab3878) – Force & Friction 1 – elder – (209) 1 This print-out should have 22 questions. Multiple-choice questions may continue on the next column or page – fnd all choices be±ore answering. 001 1.0 points A 596 kg bear grasping a vertical tree slides down at constant velocity. The acceleration o± gravity is 10 m / s 2 . What is the ±riction ±orce that acts on the bear? Answer in units o± N 002 1.0 points Which ±orces are opposite but equal? 1. ²uid 2. ±rictional 3. unbalanced 4. balanced 003 1.0 points Weight is measured in 1. kilograms. 2. m/s/s. 3. Newtons. 4. Pascals. 004 1.0 points You new motorcycle weighs 2570 N. The acceleration o± gravity is 9 . 8 m / s 2 . What is its mass? Answer in units o± kg 005 (part 1 of 2) 1.0 points * EXTRA CREDIT * Consider the 68 N weight held by two cables shown below. The le±t-hand cable is horizon- tal. 68 N 54 a) What is the tension in the cable slanted at an angle o± 54 ? Answer in units o± N 006 (part 2 of 2) 1.0 points b) What is the tension in the horizontal cable? Answer in units o± N 007 1.0 points A 299 N bag o± nails ±alls at its terminal (maximum) speed. How much air resistance acts on the nails? Answer in units o± N 008 1.0 points A spherical mass rests upon two wedges, as seen in the fgure below. The sphere and the wedges are at rest and stay at rest. There is no ±riction between the sphere and the wedges. M The ±ollowing fgures show several attempts at drawing ±ree-body diagrams ±or the sphere. Which fgure has the correct directions ±or each ±orce? Note: The magnitude o± the ±orces are not necessarily drawn to scale. 1. normal normal weight weight

Since the sphere is not moving, no forces act on it. 4. normal weight weight 5. weight 6. weight normal normal 7. weight friction friction normal normal 8. weight normal 9. weight normal normal 009 (part 1 of 2) 1.0 points A book weighing 24 N is placed on a table. How much support force does a table exert on the book? Answer in units of N 010 (part 2 of 2) 1.0 points What is the net force on the book in this case? Answer in units of N 011 1.0 points A 4 . 1 kg bucket of water is raised from a well by a rope. The acceleration of gravity is 9 . 8 m / s 2 . If the upward acceleration of the bucket is 2 . 8 m / s 2 , ±nd the force exerted by the rope on the bucket. Use g = 9 . 8 m / s 2 . Answer in units of N 012 (part 1 of 2) 1.0 points Four forces act on an object. F 1 F 4 F 2 F 3 If the object is accelerating to the right, compare the forces. 1. F 1 < F 2 , F 3 < F 4 2. F 1 = F 2 , F 3 > F 4 3. F 1 = F 2 , F 3 = F 4 4. F 1 = F 2 , F 3 < F 4 5. F 1 > F 2 , F 3 < F 4
