The height of the ball when it leaves the horizontal projectile is at 93.5cm or .935m. The velocity of the ball was .0674 seconds in the range of .1 meter. Creating a total velocity of 1.484m/s. To calculate the hang-time the formula: y= -4.9t^2 was used. The hang time is used to figure out how long the ball will be in the air for. After you find the answer, the time is then multiplied by the velocity to get the range.
The horizontal velocity does not affect the hang time because in the equation to figure out the hang time y= -4.9t^2, there is no variable for velocity. The horizontal does affect the range because to calculate the range with the equation of x= Vxt, the variable for velocity is present. The lab showed that the horizontal and vertical motion are completely independent from looking at the velocities of both. The horizontal velocity never changed; it was constant and cannot be changed by the height, whereas the vertical velocity can be. Depending on the height the velocity is changing constantly because of the hang-time. In conclusion, the two velocities are independent because they don’t affect one another or that they don’t get affected by the same variable. …show more content…
