    How Does a Catapult Calculate Force and Initial Velocity for a Projectile?

    Oops...sorry about that. *Given Information* 1.) mass of 200 kg 2.) t = 2 sec 3.) change in Y1 = 12 m 4.) X1 = 50 m, X2 = 75 m, total X of 125 m*Formulas* 1.) (change in Y) = V(init)^2 sin^2(theta)/2g -------> theta = tan-1[(4*(change in y))/x] 2.) x = 2V(init)sin(theta)cos(theta)/g 3.)...

    How Does a Catapult Calculate Force and Initial Velocity for a Projectile?

    Please,I need help with this problem... You are launching a 200kg projectile over the castle wall and trying to hit the keep. If the catapult holds the projectile for 2 seconds before releasing what is the average force delievered by the catapult? The keep itself is located 75 meters...
