3. A skateboarder with a mass of 55.0 kg prepares to skate a down a ramp with an angle of incline of 0= 35.0° and a coefficient of kinetic friction of 0.300. At the bottom of the ramp it turns into a quarter-pipe with a smooth surface (negligible friction). The skateboarder pushes off at the top of the ramp at a height of h with a speed of 3.00 m/s. The maximum height they reach on the quarter pipe is 1.75 m (vertical height). a. What is their speed when they leave the ramp? b. From what height h on the ramp did they start? h
