Question:

Two objects collide and bounce off one another. After the collision, object m1 = 1.67 kg moves off at 14.5 m/s at a heading of 327 degrees. Object m2 = 1.66 kg moves off at 8.9 m/s at a heading of 211 degrees. Initially, m2 was traveling at 11.8 m/s at a heading of 318 degrees. What must have been the initial velocity of m1? Give the speed for your first answer and the compass heading for your second answer.

Conservation of Momentum:

The conservation of momentum defined as when two particles collide with each other than the initial momentum of the particles are equal to the final momentum of the particles. The mass of the particles remains the same during the collision.

Given data:

  • Mass of object 1, {eq}{m_1} = 1.67\;{\rm{kg}} {/eq}
  • Speed of object 1 after collision, {eq}{v_{1f}} = 14.5\;{\rm{m/s}} {/eq}
  • Angle of...
