2. Now use conservation of momentum to analyze the perfectly inelastic collision of the marble and the pendulum mass. Find an expression for the velocity of the marble before it collides with the initially motionless pendulum (show your work). Hint: mvo = (m + M)v1 BIUSE E E V=9760.8 Score: 0/5 3. Select Trial 1 in the video and measure the total length of the ballistic pendulum and the maximum angle reached by the ballistic pendulum after the impact. Use these values to estimate the initial velocity of the marble. The marble mass is m - 10 0.1g, the mass of the ballistic pendulum is M - 578 0.1g.
