A lot of the time, I don't know exactly where to start (at all). My instinct here was to draw a force diagram, figure out friction, do a billion different things to get Forcenet. But actually I asked my teacher and all I needed was to draw a triangle to figure out the height for part A. So...

Fparallel = Fgsin30 = (49.1 N ) sin 30 = 24.6 N Ffriction? I don't have the coefficient of friction, so how can I figure out my Fnet?

Homework Statement Starting from rest, a 5.0 kg block slides 2.5 m down a rough 30.0 degree incline in 2.0 seconds. Determine the following: a. work down by the force of gravity b. the mechanical energy lost due to friction c. the work done by the normal force between the block and the...
