Current Attempt in Progress A block is sent up a frictionless ramp along which an x axis extends upward. The figure 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 6.00 m/s, what is the normal force on the block? K. K (J) 0 2 x (m) Number H Units v
