(a) The emu is moving to the north with speed of
the acceleration must be negative (the time is always positive), so its in the opposite direction of the speeds, which
is to the north. And it has a magnitude of
(b) Assume that the acceleration remains constant, we can get the final velocity after additional time of 2s, so
the final speed is therefore:
