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 the front of the cannon. Using the video, you measure the position of the turkey to be x = 1.66 m at t = 2.4 millisecond, and then measure the position of the turkey to be x = 2.77 m at t = 14.6 millisecond. 1 millisecond = 10-3 second Assuming the velocity is constant over this time, what is the turkey’s velocity? Give your answer in units of m/s, but do not include the units in your answer. Be sure that your units are correct for your answer. Give your answer to at least three significant figures. Your answer will not be graded on the number of significant figures. Giving three or more significant figures in your answer will avoid having it counted as incorrect due to rounding.
Explanation / Answer
Velocity = change in position/change in time = (2.77 - 1.66) m / (14.6 - 2.4) *10-3 s = 90.984 m/s
