Unformatted text preview: Oregon State University Physics 201 Midterm Exam #2 Fall Term, l 2009 Form A General directions : Only one sheet of paper (8.5 x 11both sides), with only handwritten notes, may be used during this exam. You may use any kind of calculator, provided that it is not part of a PDA, cell phone, palmtop or laptopand that it is not transmitting any information wirelessly. Physical constants and other possibly useful information are provided here. Answer Question #1 f rst. Physical constants and other possibly useful information: g = 9.80 m/s 2 Question #1: What is the Form designation (A, B, C, D, E, F or X) for your examshown at the top of this page? Write this letter in the answer box for Question 1 on the rst answer sheet in the exam booklet. For questions 2- 16 : For multiple-choice or true/false items, write the letter of the one best answer in the appropriate box on the answer sheet. For questions requiring short answers (a word or short phrase only), write those in the spaces provided. Youre graded on your answers onlyno need to show work. Assume 3 signi cant digits and SI units in all numeric answers unless instructed otherwise. True/False (4 points each) 2. True or false? When the speed of a moving object is increasing, velocity can be negative. T 3. True or false? A projectile launched vertically down- ward has a different acceleration as another projectile launched horizontally. F 4. True or false? If C = A + B (all vectors), then it must be true that || C || || A || + || B ||. T 5. True or false? When an objects velocity is constant, so is its acceleration. T 6. True or false? If a bullet is red at a 29.3 angle from shoulder height along a level road, its impact speed on the road will be greater than its initial speed from the gun. T 7. True or false? The vertical displacement of a projec- tile is always zero at the peak of its motion. F Brick A: 19.6 m/s Brick B: 22.6 m/s Short Answer (4 points each) 8. Vector e A has a magnitude of 5.00 m, directed at 30.0 above the positive...
