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 500.00kg object is moving directly east at an unknown velocity when it collides with a 600kg stationary object. After the collision, the 500.00kg object is travelling at a velocity of 16.00m/s N50.0E and the 600kg object is travelling at a velocity of 16.3m/s S38E. What was the velocity of the 500.00kg object before the collision? is energy conserved in this problem?
