Frictionless Ramp and Graph Analysis
Please explain how to interpret the graph... because i could not interpret the graph i was unable to do the rest of the problem.

A dated box of dates, of mass 9.10 kg, is sent sliding up a frictionless ramp at an angle of θ to the horizontal. Figure 5-43 gives, as a function of time t, the component vx of the box's velocity along an x axis that extends directly up the ramp. What is the magnitude of the normal force on the box from the ramp?
