In terms of the variables given in GL Fig. 9.1, what is the momentum of the system immediately after the mass m becomes embedded in the pendulum bob?
The momentum of the system immediately after the mass
Answer to Problem 1EP
The momentum of the system immediately after the mass
Explanation of Solution
In the ballistic pendulum arrangement shown in GL Figure 9.1, a projectile of mass
Immediately after the collision, the momentum of the system can be computed by taking the product of the combined mass and the velocity with which it start moving. The combined mass of the system will be
