Final Exam Sample: you will need to bring a SCANTRON Form No 882-E (100 questions in green) There will be approximately 20 conceptual and problems multiple choice questions. Besides the multiple choice questions, there will be three problems where you will have to show your work. The two problems will be similar to the multiple choice problems of this sample; each problem will have different items. Multiple Choice (choose only 1 answer question): 1. A v vs. t graph is drawn for a ball moving in one direction. The graph starts at the origin and at t = 5 s the acceleration of the ball is zero. We know that at t = 5 s, a. the slope of the curve is non-zero. b. the velocity of the ball is not changing. c. the curve is not crossing the time axis. d. the curve is at v = 0, t = 0. 2. Norma releases a bowling ball from rest; it rolls down a ramp with constant acceleration. After half a second it has traveled 0.75 m. How far has it traveled after two seconds? a. 1.2 m b. 4.7 m c. 9.0 m d. 12 m 3. Two objects of different mass are released simultaneously from the top of a 20-m tower and fall to the ground. If air resistance is negligible, which statement best applies? a. The greater mass hits the ground first. b. Both objects hit the ground together. c. The smaller mass hits the ground first. d. No conclusion can be made with the information given. 4. Vector A points north and vector B points east. If C = B A , then vector C points: a. north of east. b. south of east. c. north of west. d. south of west. 5. A baseball is thrown by the center fielder (from shoulder level) to home plate where it is caught (on the fly at shoulder level) by the catcher. At what point is the magnitude of the acceleration at a minimum? (air resistance is negligible) a. just after leaving the center fielder’s hand b. just before arriving at the catcher’s mitt c. at the top of the trajectory d. acceleration is constant during entire trajectory
