You are designing a new roller-coaster. The main feature of this particular design is a vertical circular loop. At the top of the loop, riders will feel like they are weightless when they are completely upside-down. Explain why such an effect is independent of the mass of the rider. Compute the radius of the loop required for this effect to occur if the coaster start at rest a height of 80m above the ground, speeds up as it descends to ground level, and then enters the loop.(You can assume that the coaster rolls on the track without friction).

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.

formula.

example:

given values:

mass = 0.3 kg.

the answer is the last option

explanation:

because in order to know what the molecule is you need to know how many atoms of each element are in the molecule.
