The car travels around the portion of a circular track having a radius of r = 500 ft such that when it is at point A it has a velocity of 2 ft/s, which is increasing at the rate ofa = 0.002t in ft/s, where t is in seconds. Determine the magnitudes of its velocity and acceleration when it has travelled three-fourths the way around the track. A po car enters the circular portion of a track that has a
