(6 pts) Calculate the kinetic energy of the system prior to collision. KE; = Imv2 = p2/2m 2. (6 pts) Calculate the kinetic energy of the system immediately after collision, KE. 3. (6 pts) Calculate the fractional energy loss: fract. loss = |(KE, - KE;)|/KE; 4. (6 pts) Compute the mass ratio comparing the mass of the projectile alone to the total mass of the projectile-pendulum system and compare with the fractional energy loss. 5. (6 pts) Is there a violation of the law of conservation of energy in this inelastic collision (is there energy missing)? Explain in your own words, be specific
