A block is sent up a frictionless ramp along which an x axis extends upward. Figure 7-33 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 = 40.0 J. If the block's initial speed is 4.00 m/s, what is the normal force on the block?
