What is the slope between the two points and

no friction). She collides with her friend, weighing 60 lb, at point B, 140 feet down the slope. After colliding, they travel together down the slope on the sled. The slope is maintained, but the ice is a little rougher, with a coefficient of friction of μk = 0.20. a) How fast will they be moving immediately after they collide? b) Will they come to a stop after the collision? If so, how far will they travel until they do? If not, what will their acceleration be?

x – 3y = 4 d) y + 3 = 4x

rest. The current unit that our teacher has us on so far is centripetal motion, and I can't recall being taught how to solve this. File attached below shows my work so far, I don't necessarily need the work done for me, but I just want to be put on the right track, such as an equation to start with or what I need to look for. The answer I got was clearly incorrect for part a (which is what I need help with), so please help me get going in the right direction.
