Patel (pnp223) – homework 18 – Turner – (92160) 1 This print-out should have 13 questions. Multiple-choice questions may continue on the next column or page – find all choices before answering. 001 10.0 points Consider a frictionless roller coaster such as depicted below. The acceleration of gravity is 9 . 8 m / s 2 . 27 m A B C h A Passenger cars start at point A with zero initial speed, accelerate as they go down to point B, swing around the circular vertical loop B C B of radius 27 m, then go on towards further adventures (not shown). When a car goes through the top of the loop (point C), the passengers feel weightless (for just a moment). What is the height h A of the starting point A above the loop’s bottom B? Answer in units of m. 002 (part 1 of 3) 10.0 points The figure is a graph of the gravitational po- tential energy and kinetic energy of a 72 g yo-yo as it moves up and down on its string. The acceleration of gravity is 9 . 81 m / s 2 . 0
