ME 274: Basic Mechanics II Spring 2012 February 8, 2012 Problem 1 (20 points): Given: Particle P is able to slide along a rigid guide whose shape is given in terms of its Cartesian components as: y ( x ) = 2 x 2 8, where x and y are given in meters. The y -component of the velocity of P is a constant 8 m/s. Find: When particle P is at the position of x = 2 m: (a) Determine the Cartesian components for the velocity and acceleration of P. (b) Determine the rate of change of speed and the radius of curvature for the path of P. Exam 1 Page 2 of 7
