SOLVED: In the ballistic pendulum experiment, the velocity of the projectile was measured and recorded (vo = 4.0 m/s). The mass of the projectile was 19.0 g and the ballistic pendulum mass was 76.0 g. After the projectile is fired, it hits the ballistic pendulum, and both moved with velocity. Calculate the maximum height that the ballistic pendulum (with projectile) reached after the collision.
