Particle Kinematics Homework Problems ME 274 x y path of P P Problem I/1 Particle P moves within the x-y plane on a path described by y x ( ) = 2 4 x 2 + 12 , where both x and y are given in feet. Determine the acceleration of P. Write your answer as a vector in terms of its x-y components. Use the following parameters in your analysis: x = 3 ft , ! x = 6 ft / sec and !! x = ! 2 ft / sec 2 .

Particle Kinematics Homework Problems ME 274 Problem I/3 A particle P travels in the x-y plane with a path whose coordinates are given as a function of time t as: x t ( ) = 16 ! 12 t y t ( ) = 2 + 15 t ! 3 t 2 where x and y are given in meters and t is given in seconds. a) Determine the velocity and acceleration of P in terms of their x-y components. b) Make a sketch of the velocity and acceleration vectors for P. c) Determine the rate of change of speed of P and the radius of curvature for the path of P. Use t = 8 seconds in your analysis.
