Anyways, in my physics class we did a projectile lab. We had a projectile launcher that stood a few inches above the table (from a mount) and we shot the projectile horizontally. I'm now asked to calculate the initial velocity with which the ball left the launcher, but I'm a bit confused what to consider as my range. If I remember my professor correctly, the distance traveled by the ball from the launcher over the table and before going over is negligible. The range would be considered from where the table ends to where the projectle landed. That is if I understood correctly. I would appreciate anyone who's familiar with the projectile lab correct me if I'm wrong or reaffirm what I'm thinking. Thanks!
