Askier with a mass of 50 kg starts from the top of a hill (at rest) at height h above ground. the skier glides down the hill to point a where her velocity is va = 20 m/s and continues up a second hill 8 meters high and back down the other side. her entire trip up to point c is frictionless. at point c she begins stopping and comes to a complete stop 48 meters later at point d. frictionless gliding frictionless gliding va 20 m/s stopping 43 mi.) what is the height h of the first hill? a. h = 12.8 mb. h = 32.5 mc. h = 16.5 md. h = 28.6 me. h = 20.4 mii.) what is the speed of the skier at point b? a. 0 m/sb. 12.8 m/sc. 15.6 m/sd. 18.3 m/se. 20 m/siii) what is the speed of the skier at point c? a. 0 m/sb. 12.8 m/sc. 15.6 m/sd. 18.3 m/se. 20 m/s
