Since the bullet undergoes uniform acceleration, its average speed while inside
the dog is 1/2 of (initial speed + final speed) = 1/2(100 + 0) = 50 m/s .
It travels 6 cm at that average speed.
Time = (distance) / (speed) = (6 cm) / (50 m/s) = (0.06 m) / (50 m/s) = <u>0.0012 sec</u>
(1.2 milliseconds) .
