5 (a)The x-coordinate of a particle in curvilinear motion is given by x = 3.7t3 - 4.5t where x is in feet and t is in seconds. The y-component of acceleration in feet per second squared is given by ay = 1.7t. If the particle has y-components y = 0 and vy = 3.4 ft/sec when t = 0, find the magnitudes of the velocity v and acceleration a when t = 5.9 sec. Sketch the path for the first 5.9 seconds of motion, and show the velocity and acceleration vectors for t = 5.9 sec.

The x-coordinate of a particle in curvilinear motion is given by x = 3.71³-4.5t where x is in feet and t is in seconds. The y-component of
acceleration in feet per second squared is given by a, 1.7t. If the particle has y-components y = 0 and v, - 3.4 ft/sec when t=0, find
the magnitudes of the velocity v and acceleration a when t = 5.9 sec. Sketch the path for the first 5.9 seconds of motion, and show the
velocity and acceleration vectors for t= 5.9 sec.
