I guess I am just not getting it...

Here I attached the problem to make it easier. it is #3

We are supposed to find the total work done and then find the work done by 1 crossing and divide total/1 crossing to find the number of crossings across the frictional surface. It will cross more than once, i am sure of this because everything else in the system is frictionless

going once across the rough patch

A 7.50kg block slides down a frictionless ramp of height 2.25m at a velocity of 1.50 m/s. it crosses a rough patch that is 2.5m long and exerts a force of 3N. It then continues to the other side of the ramp which is angled at 35 degrees(I don't think this matters b/c it is frictionless). How can...
