The land speed record of 13.9 m/s (31 mi/h) for birds is held by the Australian emu. An emu running due south in a straight line at this speed slows down to a speed of 12.0 m/s in 3.3 s.

Assuming that the acceleration remains the same, what is the bird's velocity after an additional 3.7 s has elapsed?

i know that you have to use...

A = ((Vfinal - Vinitial)/(Tfinal - Tinitial))

So we're solving for Vfinal.. For Vinitial, it would be 13.9m/s? And A would be -12m/s (neg. because slowing down). And for time.. would it be 7 sec-0 sec.?

thanks
