This is an assignment from my physics class that counts for 1/3 of my midterm mark. It's suppose to be basic ... I think .. but I just don't know where to start.
Here's the question Illustrated
A pulley device is used to hurl projectiles from a ramp (kinetic friction = 0.26) The 5.0 kg mass is accelerated from rest at bottom of 4.0m long ramp by a falling 20.0kg mass suspended over frictionless pulley. Just as the 5.0 kg mass reached the top of the ramp it detached from the rope (neglecting mass of the rope) and becomes projected off the ramp. Determine the horizontal range of the 5.0 kg mass from the base of the ramp.
Anything will help, even guesses.
