Wow, apparently I can't read. And yes, I found that post but I think my setup is different then theirs but still correct. I know get a value of 27.9523 N for the normal force.

Oops! Sorry, forgot to include this image http://www.webassign.net/hrw/7-33.gif It's a scale of 38 J so, at the top (0m) E=38J(4)=152 J

Homework Statement 1.A block is sent up a frictionless ramp along which an x-axis extends upward. The figure below gives the kinetic energy of the block as a function of position x; the scale of the figure's vertical axis is set by Ks = 38.0 J. If the block's initial speed is 4.70 m/s, what is...
