7. The figure below shows a ballistic pendulum, where an object of mass m is fired with some initial speed v, into a hanging mass M, which is suspended by a rod of negligible mass. After the collision the two masses stick together and swing along an arc, eventually reaching a maximum height h. Choose what kind of collision this is and then use the following values to determine h (how high the two masses swing upward): m = 0.015 kg, M = 0.200 kg, vo = 30 m/s. Hint: Use conservation of linear momentum and then conservation of mechanical energy. A) Elastic, 0.22 m B) Inelastic, 0.22 m C) Elastic, 3.2 m D) Inelastic, 3.2 m E) Inelastic, 0.16 m To L M -M+m V=0
