A cow is grazing in a field. By observing the path that she cuts through the grass, you find that her velocity is: v=(0.3ms0.07ms3t2)i^+(0.4ms2t)j^ What are the magnitude and direction of her acceleration at t = 10 s? Assume that the positive x-direction is east and the positive y=direction is north. Select one: a. a=1.5m/s2;=15.9 north of east b. a=7.8m/s2;=59.2 south of east c. a=28.3m/s2;=45 south of east d. a=1.5m/s2;=19.2 north of east
