Particle Models in Two­Dimensions Test For all questions on this test assume air resistance and friction to be negligible forces unless otherwise specified. Put your calculator in degree mode. You may use g = 10 m/s2 (or 9.8 m/s2 ) as you wish throughout this test v = x/t a = v/t v = at + vo x = ½at2 + vot v2 = vo 2 + 2ax sin = opp/hyp cos = adj/hyp tan = opp/adj Multiple Choice: (2 pts each) For the following, write the letter of the best response in the blank provided. _____ 1. If a freely falling object were somehow equipped with an odometer to measure the distance it travels, then the distance it travels each succeeding second would be A. the same. B. less than the previous second. C. greater than the previous second. D. The distance cannot be predicted. _____ 2. If a freely falling object were somehow equipped with a speedometer, then the speed it gains each succeeding second would be A. the same. B. less than the previous second. C. greater than the previous second. D. The speed cannot be predicted. _____ 3. Starting from rest, a freely-falling object will fall, in 10 seconds, a distance of about A. 10 m. B. 50 m. C. 100 m. D. 500 m. E. more than 500 m.
