Goal: Find how much work is being done when you smash a birdie.

Procedure: 1. Find mass of the birdie. 2. Time how long it takes from when the birdie hits the raquet until it hits the ground. 3. Measure how far the birdie traveled from when it was hit by the raquet. 4. Find the velocity using our previous calculations. 5. Find the acceleration from using the motion sensor. 6. Find the force by using our previous calculations. 7. Take the force times the distance traveled to find the work. 8. Find kinetic energy from using our other data.

<span style="font-family: Georgia,serif;">In our lab we concluded that when smashing a birdie with a badminton raquet, the work being done on the birdie was 309.275 joules of work. We started out by finding the mass of the birdie which is 5 grams. We then timed how long it takes the birdie to hit the ground from the moment it hits the face of the raquet. We took a meter stick and placed it from where Emma stood and hit the birdie to the place where the birdie landed. We measured a distance of 4.6 meters. From this data we could find the velocities, which are: Vi after birdie was tossed up, 11.795 m/s, Vi before the birdie was hit, 9.675 m/s, Vf after the birdie was hit, 22.678 m/s. From there we proceeded to find the acceleration by finding the change in velocity divided by the change in time, 13.4467 m/s/s. We also found the kinetic energy which is 347.257 joules. This makes sense because the velocity of the birdie increases immidiatly when coming in conctact with the face of the raquet. Therefore, work was being done on the birdie.
