\"Note: The collision shown below is a top-down view. Imagine that the process is occurring on a frictionless table and that you are looking down at it.* Two objects of mass 2-kg and 4-kg, respectively, collide and combine into a 6-kg mass. Before the collision, the 2-kg object was seen traveling at 10-m/s directly towards the night, while the 4-kg object was seen traveling at an unknown speed m a direction of 60 degrees above the hornizontal, After the collision the combined objects travel at an unknown speed in a direction of 30 degrees above the horizontal. The system is shown below. a. Determing the speed of the 4-kg object before the collision (10pts) b. Determine the speed of the 6-kg object after the collision (10pts) c. Determine what percentage of the initial energy (if any) is lost in the collision? ( 10pts)
