Show me how to solve it step by step , thanks in advance 1. *Note: The collision shown below is a top-down view. Imagine that the process is occurring on africtionless 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 in a direction of 30 degrees below the horizontal, while the 4-kg object was seen traveling at an unknown speed in a direction of 40 degrees above the horizontal. Thesystem is shown below. After the collision the combined object travels directly towards the right.a. Determine the speed of the 4-kg object before the collisionb. Determine the speed of the 6-kg object after the collision2-kgBefore:10-m/s30°4-kgV₁₂ =?40°After:X-?6-kg
