For the following question, state the type of collision and solve the problem. Draw a diagram, use components, use proper significant digits, and determine if energy is conserved. Show your work in clear, detailed steps.

1. A 62.000kg object heading directly west at 3.0000m/s collides with an 80.00000kg object heading directly north at 3.500000m/s. If these two masses stick together upon collision, what is their velocity after collision? Is energy conserved in this problem?
