A ball of mass 4.6 g strikes a ballistic pendulum mass of 3.3 kilograms. The center of mass of the pendulum rises a vertical distance of 14 centimeters. Under the assumption that the bullet remains embedded in the pendulum, calculate the initial velocity of the ball.

M is the mass of the ball, the pendulum of mass m, V the velocity of the ball at the beginning, and V-speed-tilt-ball system after the collision.
ReplyDeleteEnergy savings:
1 / 2 (m + M) V ² = (m + M) GH
V ² = 2GH
Conservation of momentum:
mv = (m + M) V
v = (m + M) sqrt (2 Ghz) / m
v = [3.3046/0.0046] sqrt (2 * 9.8 * 0.14) m / s
Energy is not preserved in inelastic collisions
