A projectile weighing 8.56 grams is fired into a soft clay pendulum bob weighing 2.41kg. the projectile impacts the pendulum bob and remains imbedded in it after the collision. Following the impact, the pendulum bob swings to a position placing its center of mass 6.51 cm above its pre-impact position. (no friction or air resistance)
1. what kind of collision does this impact represent?
2. what is the kinetic energy of bob as it reaches its highest point?
3. what is the potential energy of the bob as it reaches its highest point?
4. what was the speed of the projectile as it impacted the bob?
5. what is the speed of the bob as it returns to its starting position prior to impact?
