The x-coordinate of a particle in curvilinear motion is given by x = 4.7t - 3.1t where x is in feet and t is in seconds. The y-component of acceleration in feet per second squared is given by a, = 3.8t. If the particle has y-components y 0 and v, = 5.3 ft/sec when t = 0, find the magnitudes of the velocity v and acceleration a when t = 5.2 sec. Sketch the path for the first 5.2 seconds of motion, and show the velocity and acceleration vectors for t = 5.2 sec. IVy Answers: V = ft/sec a = ft/sec2
