Asked by victoria c
An Australian emu is running due south in a straight line at a speed of 16.9 m/s and slows down to a speed of 13.9 m/s in 3.5 s.
Assuming that the acceleration remains the same, what is the bird's velocity after an additional 2.0 s has elapsed? (Assume that due south is the positive direction. Indicate the direction with the sign of your answer.)

a=(V-Vo)/t=(13.9-16.90)/3.5=-0.769m/s^2
V = Vo _ a*t
V = 13.9- 0.769*2 = 12.4 m/s.
V = Vo _ a*t
V = 13.9- 0.769*2 = 12.4 m/s.
