Physics 220 Final Exam (Version A) Summer 05 THIS EXAM CONTAINS 36 QUESTIONS. ANSWERS ARE ROUNDED. PICK THE BEST ANSWER TO EACH QUESTION. Each of the following questions (I - 15) is worth 6 points 1. In the produce section of a supermarket, five pears are placed on a spring scale. The placement uf the pears stretches the spring and causes dial to move from zero a reading of 2.0 kg. If the spring constant is 450 N/m. what is the disp t acelnent of the spring due to weight of the pears'? 2. Gina's favorite exercise equipment at the gym consists of various springs. In one exercise, she pulIs a handle grip attached to the free end of a spring 0.80 m from its unstrained position. The other end of the spring (spring constant = 53 N!m) is held in place by equipment frame. What the magnitude of force that Gina is applying the handle grip? Page I
