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-

FI R %24 Part A A ball of mass m moving with velocity v strikes a vertical wall as shown in (Eigure 1). The angle between the ball's initial velocity vector and the wall is 6 as shown on the diagram, which depicts the situation as seen from above. The duration of the collision between the ball and the wall is At, and this collision is completely elastic. Friction is negligible, so the ball does not start spinning. In this idealized collision, the force exerted on the ball by the wall is parallel to the x axis. What is the final angle Or that the ball's velocity vector makes with the negative y axis?
