Unformatted text preview: armington (kma786) – 5.4 – Stepp – (55860) 1 This print-out should have 9 questions. Multiple-choice questions may continue on the next column or page – find all choices before answering. 001 (part 1 of 4) 10.0 points A Calculus student begins walking in a straight line from the RLM building towards the PCL Library. After t minutes his velocity v = v ( t ) is given (in multiples of 10 yards per minute) by the function whose graph is 2 4 6 8 10- 2 2 4 6- 2 t v How far is the student from the RLM build- ing at time t = 4? 1. dist = 160 yards 2. dist = 140 yards 3. dist = 110 yards 4. dist = 130 yards 5. dist = 120 yards correct Explanation: The student is walking towards the PCL Library whenever v ( t ) > 0 and towards RLM whenever v ( t ) < 0. The distance he has walked is given by 10 times the area between the graph of v and the t axis since 1 unit is equivalent to 10 yards. Now at t = 4 this area is 12 units, so the student has walked a distance of 120 yards. 002 (part 2 of 4) 10.0 points How far is the student from the RLM build- ing at time t = 8? 1. dist = 340 yards 2. dist = 300 yards correct 3. dist = 320 yards 4. dist = 310 yards 5. dist = 290 yards Explanation: The distance the student has walked is given by the area between the graph of v...
