The x-coordinate of a particle in curvilinear motion is given by x = 5.3t³ - 2.2t where x is in feet and t is in seconds. The y-component of acceleration in feet per second squared is given by ay = 5.5t. If the particle has y-components y = 0 and vy = 2.8 ft/sec when t = 0, find the magnitudes of the velocity v and acceleration a when t = 4.4 sec. Sketch the path for the first 4.4 seconds of motion, and show the velocity and acceleration vectors for t = 4.4 sec. Answers: V = a = i 305.636 141.997 ft/sec ft/sec²
