The Raptor is an outside loop roller coaster in which riders are belted into seats resembling ski-lift chairs.
1, Draw the Free-Body-Diagram of the rider at the highest position in the loop.
2. Calculate, using the work and energy method, the velocity V1 of the rider at the highest position in the loop
3. Determine the minimum speed V0, at which the seat Should coast down from the top of the hill, so that passengers can just make the loop without leaving contact their seats.
Neglect friction, the size of the car and passenger, and assume each passenger and car has a
mass m. Hint: the rider is upside down and belted to the seat at the position interest.
