*Note: The diagram shown below is a top-down view. Imagine that that process is occurring on a table and that you are looking down at it.* Two projectiles of mass 4-kg and 12-kg traveling at 10-m/s and 20-m/s, respectively, undergo a completely inelastic collision at the intersection of their lines of travel, as shown below. Prior to the collision the projectiles travel along a frictionless surface; however, after the collision the surface is rough and is characterized by a coefficient of kinetic friction of 0.15. At what angle should a spring of constant 80-N/m be placed in order to “catch” the projectiles after the collision? If the spring is located 4-m away from the collision point, what will be the maximum compression of said spring?
