A skateboarder is going to ride down one ramp and then up another. She wants to come down the first ramp and go up the second ramp to a height of exactly 3 m without kicking off or adding any other energy. Together the skateboard and skateboarder have a mass of 72 kg, and she will lose approximately 210 J of energy to friction. g = 9.8 m/s^2. Calculate the required starting height of the skateboarder in order for her to reach 3 m.
