A projectile of mass is traveling at a constant velocity
Chapter , Problem 66(choose chapter or problem)
A projectile of mass is traveling at a constant velocity toward a stationary disk of mass M and radius R that is free to rotate its axis (Figure 10-54). Before impact, the projectile is traveling along a line displaced a distance b below the axis. The projectile strikes the disk and sticks to point B. Model the projectile as a point mass. (a) Before impact, what is the total angular momentum of the diskprojectile system about the axis? Answer the following questions in terms of the symbols given at the start of this problem. (b) What is the angular speed v of the diskprojectile system just after the impact? (c) What is the kinetic energy of the diskprojectile system after impact? (d) How much mechanical energy is lost in this collision?
