2. In Lab 7 you used a ballistic pendulum to measure the speed of a ball propelled by a projectile launcher. The ballistic pendulum can be considered a solid rod rotating around an axis at one end, as in the diagram: 24.5 ст mpall Vrotal Vball Mtotal Mpend In the lab, I measured the following initial conditions: Mass of the ball, mpall = 10 g Mass of the pendulum, mpend = 242 g Length of pendulum, l = 24.5 cm For the angle the pendulum is deflected, I found 0 = 0.17 rad and assumed the time for the deflection is 50 ms. Equate the expressions for the kinetic energy of the ball/pendulum combination and for the kinetic energy of rotation to find the velocity of the ball/pendulum combination, and then use conservation of momentum to find the initial velocity of the ball How does the velocity compare
