2/107 A particle moves on a circular path of radius r = 0.8 m with a constant speed of 2 m/s. The veloc- ity undergoes a vector change Av from A to B. Ex- press the magnitude of Av in terms of u and 40 and divide it by the time interval At between A and B to obtain the magnitude of the average acceleration of the particle for (a) A0 = 30°, (b) 40 = 15°, and (6) (c) 40 = 5°. In each case, determine the percent- age difference from the instantaneous value of acceleration. = VB B. r = 0.8 m Av VA 40 VB ΔΘ VA A A Problem 2/107
