1. The problem statement, all variables and given/known data So does anyone here know a lot about ballistic pendulums? I was just wondering how I could calculate the distance the ball will travel horizontally when shot horizontally, from a table. 2. Relevant equations 3. The attempt at a solution I know that first, I have to calculate the velocity of the ballistic pendulum, v=(m+M)/m* sqrt(2gh). Now, my problem is, how can I measure precisely enough to predict exactly where the ball will land? Like, specifically, what is "h" ? And from this initial velocity, how do I calculate the distance using kinematics? thanks!
