I seriously need help in solving these physics problems!?

Please assist me in learning how to solve these problems, I need to learn this for a test coming soon.

In a football game, linebacker (m = 100 kg) traveling at 4 m/s to the right tackles a running back (m = 85 kg) traveling 6 m/s to the left. During the tackle, the linebacker wraps his arms around the running back, and the two then move together as one unit in the moments immediately following the collision. (See the Inelastic Collision Example Problem videos for the method to use on this problem)
(5A) What is the velocity in m/s of the running back after collision?
(5B) What is the direction of the running back after collision?
(5C) What is the kinetic energy in J of the running back before the tackle?
(5D) What is the kinetic energy in J of the linebacker before the tackle?
(5E) What is the kinetic energy in J of the pair in the system before the tackle?
(5F) What is the kinetic energy in J of the running back after the tackle?
(5G) What is the kinetic energy in J of the linebacker after the tackle?
(5H) What is the kinetic energy in J of the pair in the system after the tackle?
(5I) Was kinetic energy conserved in the collision?
(5J) Is this an elastic or inelastic collision?
