In a ballistic pendulum an object of mass m is fired with an initial speed vo at a pendulum bob. The bob has a mass M, which is suspended by a rod of length L and negligible mass. After the collision, the pendulum and object stick together and swing to a maximum angular displacement 0 as shown (Figure 1). Part B An experiment is done to compare the initial speed of projectiles fired from high-performance catapults. The catapults are placed very close to a pendulum bob of mass 10.0 kg attached to a massless rod of length L. Assume that catapult 1 fires a projectile of mass 7.00 g at speed v1 and catapult 2 fires a projectile of mass 8.50 g at speed v2. If the projectile from catapult 1 causes the pendulum to swing to a maximum angular displacement of Figure 7.20 ° and the projectile from catapult 2 causes a displacement of 10.6 °, find the ratio of the initial speeds, 1 of 1 Express your answer numerically. • View Available Hint(s) V AZO ? v = 0 v2 M -M+m-

A uniform rod of mass 200 g and length 100 cm is free to rotate in a horizontal plane around a fixed vertical axis through its center, perpendicular to its length. Two small beads, each of mass 20 g, are mounted in grooves along the rod. Initially, the two beads are held by catches on opposite sides of the rod’s center, 10 cm from the axis of rotation. With the beads in this position, the rod is rotating with an angular velocity of 10.0 rad/s. When the catches are released, the beads slide outward along the rod. (a) What is the rod’s angular velocity when the beads reach the ends of the rod? (b) What is the rod’s angular velocity if the beads fly off the rod?

Consider a head-on, elastic collision between twobodies whose masses are m and M, with Itis well known that if m has speed and M is initiallyat rest, m will bounce straight back with its speedunchanged, while M will remain at rest (to anexcellent approximation). Use this fact to predict thefinal velocities if M approaches with speed and mis initially at rest.
