Explanation / Answer

The value of the initial velocity for each trial was found to be relatively constant. The initial velocity was found by applying the kinematic equations to the measurement s taken in the lab. In the first set of trials, where the projectile was fired from a horizontal position, the initial elevation of the projectile was 84.9 cm or .849 m. The horizontal distance for the trials is shown below.

Horizontal Distance (m)

234.0 cm

0.2340 m

235.6 cm

0.2356 m

254.0 cm

0.2540 m

258.7 cm

0.2587 m

253.1 cm

0.2531 m

Average

247.1 cm

0.2471 m

Using the initial elevation as the distance traveled in the y direction the time was found using the following equation:

t= 2dyg

Where dy is the distance in the y direction and g is the acceleration due to gravity (9.80 ms2). This gave a time of 0.416 s. The average horizontal distance (0.2471 m) was divided by the time (0.416 s) to give an initial velocity of 5.94 ms.

The average horizontal distance traveled was found for each set of three trials for a given angle measure. This data is recorded in the following table:
