The particle P moves along the curved slot, a portion of which is shown. Its distance in meters measured along the slot is given by s = t 2 4 , where t is in seconds. The particle is at A when t = 2.00s and at B when t = 2.20s Determine the magnitude aavg of the average acceleration of P between A and B. Also express the acceleration as a vector ¯aavg using unit vectors ¯i and ¯j
