An Australian emu is running due north in a straight line at a speed of 13.0 m/s and slows down to a speed of 9.60 m/s in 3.90 s. (a) What is the magnitude and direction of the bird's acceleration? (b) Assuming that the acceleration remains the same, what is the bird's velocity after an additional 1.20 s has elapsed? (a) Number i 0.87 (b) Number 8.56 Units m/s^2 Units m/s +
