The x-coordinate of a particle in curvilinear motion is given by x = 4.9t³-5.2t where x is in feet and t is in seconds. The y-component of acceleration in feet per second squared is given by ay = 1.6t. If the particle has y-components y = 0 and vy = 4.5 ft/sec when t = 0, find the magnitudes of the velocity v and acceleration a when t = 2.0 sec. Sketch the path for the first 2.0 seconds of motion, and show the velocity and acceleration vectors for t = 2.0 sec. Answers: V= a= ft/sec ft/sec²
