2008年10月11日 · Roller Coaster problem! Homework Statement A roller coaster at Six Flags Great America amusement park in Gurnee, Illinois, incorporates some clever design technology and some basic physics. Each vertical loop, instead of being circular, is shaped like a teardrop. The cars ride on the inside of...

2005年3月8日 · A roller coaster car crosses the top of a circular loop-the-loop at twice the critical speed. What is the ratio of the car's apparent weight to its true weight? from my notes i have that Velocity_critical= squareroot ( r w / m) v = sqrt(rw/m) so what i did was multiply v times 2 because the problem states were going at twice the critical speed.

2014年8月17日 · A roller coaster of mass m starts on a inclined plane at a certain height, and then enters a circular loop, with radius r. At what height, h on the plane, must the trolley start in order to stop at the exact top of the loop, and then what happens? Homework Equations gpe=g*h*m total energy = KE + PE The Attempt at a Solution

2010年12月13日 · "A roller coaster car does a loop-the-loop. When it is upside down at the very top, which of the following is true?" The normal force and the weight are in opposite directions. The normal force and the weight are perpendicular to each other. The weight is zero. The normal force and the weight are in the same direction.

2004年1月17日 · Hey guys I have an assignment and I need to design a roller coaster with banked corners, a loop, and a hill. Anyway I'm having trouble finding a radius for my loop the velocity going into the loop is 39.61817765m/s formulae: a c {centripetal accelerational} = (v{velocity} 2)/r{radius} thanks guys

2008年9月28日 · Show that a roller coaster with a circular vertical loop. The difference in your apparent weight at the top of the circular loop and the bottom of the circular loop is 6 g's-that is, six times your weight. Ignore friction. Show also that as …

2010年11月10日 · Homework Statement A mass of 100kg is h meters high on a track that extends into a loop that has a radius of 20m. Assume track is frictionless. I need to find minimum height for the mass to make it around the loop without falling off or going backwards. Homework Equations Conservation...

2015年7月22日 · What is the minimum height h of a slope that must be constructed in order for a rider in the cart with a combined mass m = 80.0 kg to complete the loop with a radius r = 10.0 meters safely, assuming a frictionless trip?

2012年10月10日 · Homework Statement The Gravitron single-car roller coaster consists of a single loop-the-loop. The car is initially pushed, giving it just the right mechanical energy so the riders on the coaster will feel "weightless" when they pass through the top of the circular arc. How heavy will they...

2008年10月21日 · A roller coaster loop has a radius of 12m. If the passengers in a car are not to fall out at the top of the loop, what is the minimum speed the car must have at the top? The Attempt at a Solution Alright I think I got the right answer but I do not completely understand the question. so what i did was I went Fc=Fg (but why??) g is 9.8 mg=mv^2/r ...
