Conservation+of+Momentum



Conservation of Energy < Link to the next analysis of this crazy tennis action!!! This is how the data for the racket was found xD

O.o Mass of tennis ball : .057 grams Mass of tennis racket : 10.3 ounces (.29200008793 grams) Initial Tennis ball speed: 10.3 m/s Initial racket speed: 5.69 m/s Final tennis ball speed: 18.37 m/s Final racket speed: 2.99 m/s O.o



Conservation of Momentum M1 = M2 1 m1v1i + m2v2i = m1v1f + m2v2f 2 (.292)(5.69) + (.057 )(10.3) = (.292)(2.99) + (.057)(18.37) 3 1.661 + .5871 = .87308 + 1.04709 4 2.2481 = 1.92017

The mass of the tennis ball and racket were gathered with a balance. The velocities were found using a video analysis program that graphed the data, and the velocity is the slope of the graphs. Using the data given it was solved out to see if the numbers matched up, therefore proving conservation of momentum. The result is that the initial momentum is only .3 greater than the final momentum, giving a 17% error. Since none of the values, other than mass, could be calculated near exactly 17% is a very low amount. The video analyzing software is not perfect and has always caused a slight error to be added to the always present human error.
