Question
In your internship with the Mythbusters, you are helping measure the velocity of a frozen turkey shot out of an air cannon. Your high-speed camera shows position of the turkey and the time, the times being measured from the time the turkey leaves the cannon and the position being measured from some unimportant positoin. Using the video, you measure the position of the turkey to be x=1.00 m at t=0.010 sec, and then measure the position of the turkey to be at x= 5.70 m at t=0.083 sec. Assuming the velocity is constant over this time, what is the turkey's velocity?
Explanation / Answer
Given:
Position 1, x1 = 1.00 m
Time 1, t1 = 0.01 s
Position 2, x2 = 5.70 m
Time 2, t2 = 0.083 s
To Find: The velocity of the turkey, v
Solution:
Velocity of the turkey (if it stays constant) can be calculated as
v = (x2 - x1) / (t2 - t1) = (5.70 - 1.00) / (0.083 - 0.01) = 4.70 / 0.073
v = 64.38 m/s
Ans. The Turkey's velocity is 64.38 m/s.
