You set up a ramp as depicted to practice your skateboard skills. The ramp is a wooden board L=9.0 m long and is propped up between the ground level at one end and h=1.5 m at the other end. You approach the ramp from the right (higher ground) at 13 m/s. How fast are you once you get past the ramp (lower ground)? Assume your mass is 75 kg and a constant friction of 72 on the ramp.
