So if I find this I can find the velocity using E=1/2mv^2 instead of projectile. However it should be similar to the projectile? And was my projectile calculation correct for 0 degrees or should I have incorporated the horizontal distance? Thankyou very much for your help.

I just mean incorporating the energy into the physics equation to get a more accurate result. It is only a toy gun so all I know is what results don't sound right. So in terms of equations, would that result in an accurate answer?

Yes, that makes sense. But how could that be incorporated to find the velocity? Could that be used instead of projectiles?

okkay, so if I change it so I am calculating final velocity, won't it be the same?

Sorry I forgot to mention the bullets are fired from the same gun each time and the weight difference is about 0.2 grams maximum and the distances are ranging from 5.99m to 8.87m. I am not exactly sure how to incorporate air resistance into the equation, but there could also be an...

I am doing a projectile motion problem with my own results, and the unknown's of initial velocity and time. It is at 0 degrees, which I thought would mean I could find the vertical down of the projectile (where at an angle you find the vertical up and down because it goes up first). I have tried...
