2. The highest point on the wooden roller coaster is15m. If the average mass of a rider riding the wooden rollercoaster is 60kg and there are 20 people on the ride A)In a perfect physics 11 world, what would be the velocity on one person at the bottom of the hill? B) As an example, if one persons velocity is 12m/s (this is not the answer to part A), what is their energy lost? C) Going at 12m/s, someone sticks their hand out the side of the coaster. The reference area of their hand is 0.0112m. The density of air is 1.25kg/m 3. The drag coefficient is 0.90. What is the drag force of the persons hand?
