10 of 16 A firework explodes into three pieces as shown in the diagram below. Now that you have set up the equation for the z and y components of the final momentum of the firework, let's do some physics! Given: • The initial firework had a mass of 9.0 kg and was launched at v = 50 m/s vertically straight up. • The firework explodes into three pieces of equal mass 3.0 kg. The angles 0 = 03 = 40°. • Speed vi = 100 m/s. What is the speed v2? Note: the angles shown for mass m1 and mass m3 are relative to the horizontal r axis. Mass m, is moving straight up (y axis). m2 V2 m, V1 ma V3 Express your answer with the appropriate units. HA

3. This problem refers to the figure below: mmm There are 3 identical bobs of mass m hanging side-by-side. Two are then lifted to a height of h and released. The collisions in this problem are elastic. Answer the following questions: (a) Let's call the initial and final state immediately before and after the collision, respectively. Write down the initial momentum and kinetic energy of the system in terms of m and h. (b) Show that, after the collision, the left and center bobs rise to height h while the right bob becomes stationary. In particular, show that the center bob acts as if it were swinging freely as a lone pendulum.
