Q4. Pls help! Please SHOW ALL WORK FOR EACH PART OF THE QUESTION AND ROUND TO 4 SIGNIFICANT FIGURES! This is for a timed exam so please be legible! Will give thumbs up! Thanks

4. An 80-kg superhero sits at rest on top of a 5.0 meter wall as shown below. Using a rope, he swings toward a 70-kg villain who is initially at rest. The superhero releases the rope just before colliding with and clinging to the villain. After the collision, the superhero and villain slide together across the floor until they are brought to rest by friction. Determine; a. The velocity of the superhero just before he collides with the villain. b. The velocity of the superhero/villain system immediately following the collision. c. The impulse delivered by the floor to the combined masses. d. If the men slide across the floor over a distance of 4.75 m, apply the Work-Energy Theorem to determine the force of friction acting upon them. 5 m AX = 4.75 m
