EXPERIMENT 10. BALLISTIC PENDULUM before the collision with the velocity of ball plus pendulum after the collision, according to m b v 0 = ( m b + m p ) v r Conservation of energy relates the initial (kinetic) energy of the pendulum to its final (po- tential) energy, according to 1 2 ( m b + m p ) v 2 r = ( m b + m p ) gh where h is the maximum height reached by the center of mass of the pendulum. Using these two relations, we can determine the velocity

Unformatted text preview: v of the ball when it is shot from the cannon. Figure 10.1: The operation of the ballistic pendulum Practice 1. Consider a ball of mass m b moving with speed v colliding inelastically with an object of mass m p that is initially at rest. What is the speed v r of the two objects immediately after the collision in terms of v , m b , and m p ? 64...

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
