Part B. Determination of the Initial velocity of a Projectile from Range fall measurements:

Theory: Page 133, Data Table 2: Page 140.

Lab Report must include the following:

Four different Heights and the corresponding range for each height used in meters.

Using equation 9.7, page 135, find the initial velocity of the projectile in m/s.

V_xo= √gx²/2y

Based on data shown, if the difference exceeded 0.5 m/s between readings for the initial velocity, find the average of all the velocity readings and then determine the % difference between each of the four readings and the average of the four readings, as you would do in standard deviation.

Show all calculations of the initial velocity and % difference. You must always include the units next to each measurement throughout your calculations and not only in the final answer.
