Hi everyone, I am new here at Physics Forums and this is my first post.
Earlier this evening, my dad and I were trying to figure out the initial velocity of our projectiles. We were successful in calculating the initial velocity in a vacuum, but we are perplexed as to how to calculate the velocity in air. Here is the data we gathered:
Total distance traveled by projectile: 380ft
Time to impact from launch: 2.5 seconds
Angle of launch: 45 degrees
Temperature at time of launch: 45 degrees Fahrenheit
Dimensions of projectile: 2 inch diameter x 3 inch long cylinder
Force of gravity: 32.15223 ft/s/s
Initial Velocity in a vacuum: ~111 feet-per-second
Again, we would like to know the initial velocity of the object traveling through the air. If you can provide an answer, that's great, but we would also like an explanation to feed our starving minds :)
Cheers, and thanks in advance!
