A dated box of dates, of mass $5.00 \mathrm{kg},$ is sent sliding up a frictionless ramp at an angle of $\theta$ to the horizontal. Figure $5-41$ gives, as a function of time $t,$ the component $v_{x}$ 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?
10. The first of two identical boxes of mass m is sitting on level ground: The second box is sitting on ramp that makes 20" angle with the ground: The normal force of the level ground on the first box is N the normal force of the ramp on the second box is Na. Which statement is correct? N; =N mg mg; N; mg sin20" mg; N; mg cos 209 mg; Na mgcos 200 mg
