MAC 2311 Midterm: MAC 2311 FAU Test4C05
Document Summary
Instructions: be systematic and show all your work clearly. Candidates are warned that, if we cannot read it then we cannot grade it, and penalties will apply: there are four problems, attempt all. All problems carry equal weight, maximum scores of individual parts are shown: closed book exam. Average time per problem is 18 minutes, some problems may take longer while others take shorter. Problem 1: to a close approximation the pressure behind a ri e bullet varies inversely with the position x of the bullet along the barrel. Thus the acceleration of the bullet may be written as a = k/x m/sec2 where k is a constant and x is in meters. Problem 2: the motion of a particle is de ned in the cartesian coordinate system by parametric equations x = (2t + t2) m and y = (t2) m where t is in seconds.
