Consider a perfectly inelastic collision, where two objects collide with each other, and stick together. The net external force on the system is 0.

  • m1 = 2 kg
  • m2 = 3 kg
  • v01 = 5 m/s
  • v02 = -4 m/s

a) What is their final velocity, after the collision, in m/s? Make sure you get the correct sign.

b) How much kinetic energy was lost in the collision, in Joules?

Make up a 2D inelastic collision problem, and solve it (two objects stick together) .Your problem needs to be unique, so use masses such as 26 kg for one, 590 kg for the other, etc. They both must be moving initially, and also make sure that one of the objects’ velocity is diagonal. One can be moving in the x direction initially, but the other must have an x and y component to it’s initial velocity.
