- | On the Jovian moon of Ganymede, a team has been designing Richard’s Ragin Boar Tiger Rocket Ride. Unfortunately, | ||
- | The team needs to find the height of the first hill (h in the diagram) and the mass of Go-Gurt used to help stop the cart carrying the riders, but oh darn it! The boyfriend threw up on the paper including some of the design details leaving it only partially legible. | ||
- | The coaster starts by a rocket propelling the cart up the hill, with the rocket booster shutting off just prior to reaching the peak of the hill such that the speed of the cart is 1 m/s at the top of the hill. The cart then goes down the hill to a turning segment, where it magnetically latches onto the end of a 20 meter long, 7,500 kg nickel bar. The other end of the bar is fixed to a well-lubricated pin at the center of the semi-circular turning segment. | ||

- | Here are the designer’s notes: | ||
- | * Mass of car + passengers: 1,600 kg | ||
- | * Mass of Ganymede: | ||
- | * Mass of empty stopping cart: 1000 kg | ||
- | * Average radius of Ganymede: 2634 km | ||
- | * Speed upon exiting the turn-around and approaching the Go-Gurt: at least 14 m/s, but no higher than 16 m/s | ||
- | * Track is frictionless | ||

- | Barely legible at the bottom of the designer’s notes is scrawled: | ||
