Today, I was really angry that I bombed my physics test. In order to release my anger I threw a real cow at a surfboard. I felt sorry for the surfboard afterwards. The cow was okay though.
The formula for work is W=F*displacementX(costheta). Where W is work and F is the force. So by finding the distance traveled by the cow and the force my cannon arm applied to the cow, I could find the work done.
By finding the work done, I can also find the velocity of the cow. Unfortunately my cow was a baby and weighed too little to be registered on the scale, but by using the formula: W=KEf+0 (because there is no initial KE), because KE is 1/2*m*v^2, I could find the velocity. Alternatively, I could find the weight if I had the velocity. However, I think that even though this cow seemed to weigh a ton, the velocity would be too high for me to calculate due to the enormous amount of work done.
I could also calculate my power by dividing my work done by the time it took for the cow to hit the surfboard (.000009s?). P=J/t. Then I could find my horsepower by dividing the power (in watts) by 746...but that would be too much WORK for me to do...
