Conservation of Momentum Applications 1. Two object with masses m 1  and m 2  have equal kinetic energies. How do the  magnitudes of their momenta compare?  (a) p 1  < p 2    (b) p 1  = p 2   (c) p 1  > p 2 1.  How high does the pendulum-bullet combination rise after the collision? A rifle bullet of mass  m = 0.03 kg  traveling at  v b  = 240 m/s  collides with and embeds  itself in a pendulum of mass  M = 2.88 kg , initially at rest and suspended vertically by  massless strings of length  L = 2 m . How high does the pendulum-bullet combination rise after the collision? 2.

A bullet of mass  0.012 kg  and initial speed  400 m/s  penetrates an initially stationary pop  can of mass  0.047 kg  and emerges with a speed  290 m/s How fast is the can moving after the bullet emerges? (Friction between the can and the  surface is negligible.)  3.  A block of mass  M 1  = 3.5 kg  moves with velocity
