In a ballistic pendulum experiment, a small marble is fired into a cup attached to the end of a pendulum. If the mass of the marble is 0.0235 kg and the mass of the pendulum is 0.250 kg, how high h will the pendulum swing if the marble has an initial speed of 5.65 m/s? Assume that the mass of the pendulum is concentrated at its end so that linear momentum is conserved during this collision. h = m

Two masses undergo a collision and they stick together. M1 has a mass of 550g and was traveling at an unknown velocity toward the second mass, M2=400g, which was traveling in the same direction at 4.5m/s. After the collision, they have a velocity of 5.1 m/s. Determine the velocity of the first mass before the collision.
