Shoot Your Grade Lab Update

Last week our physics class failed at a single attempt to calculate the horizontal distance traveled by a projectile launched from a projectile launcher.  After one test launch, we were required to calculate the delta x of a ball launched at an angle of -4 degrees.  I think the biggest factor contributing to our failure was the lack of effective communication and teamwork.  When it came time to gather values to calculate the distance, the main form of communication was that of yelling louder than the next person so you could distribute your information.  With better communication, the class as a whole would have more time to work through the problem and possibly not feel the intense time crunch that we did when we were conducting the lab.  The biggest difference between the first and second shots was the fact that the -4 degree angle meant that the ball had an initial velocity in the downwards direction instead of upwards.  Once I got past that and found the y-component of the velocity vector,  I was able to find time in the air and then plug that into the second equation to find delta x.  Looking back on it, our class definitely had the brainpower to get this right the first time, we just cracked under pressure and gave into the confusion just a little bit.  Overall it was still a great lab and a fun challenge for the beginning of the year.
