Question 1 A 71.0 kg snowboarder heads down a 17.5 hill that has a height of 47.4 m. If the hill is assumed to be frictionless and there is horizontal wind with a force of 78.9 N acting against the snowboarder, find the speed of the snowboarder as they reach the bottom of the hill using work and energy. Question 2 You design a brand new type of water slide that launches a person from the top of a 30.0 m high straight slide with a compressed spring; the design is shown above, where the angle of incline is 0= 56.0. If the spring has a spring constant of 1.60E+03 N/m and is compressed by 2.20 m, what is the speed of a 52.5 kg rider at the bottom of the slide? Assume coefficient of kinetic friction between the wet person and the slide is 0.0800
