WebA toy car rolling down a loop-the-loop track demonstrates the minimum height it must start at to successfully negotiate the loop. What it shows: For an object to move in a vertical circle, its velocity must exceed a critical value vc=(Rg)1/2, where R is the radius of the circle and g the acceleration due to gravity. This ensures that, at the top of the loop, the … WebAnswer (1 of 4): Assuming the object ( car/ bike/ rollercoaster car) does not fall off the track** then it will ebtnhe sum of the two forces. The object will go fast enough such that gravity alone is not enough to supply the centripetal force and the track/surface provides a contact force pushing...

WebIf you ignore friction and propulsion (if he is giving it gas while on the loop) then KEi+ PEi = KEf + PEf. There is no PEi so then we have Initial Kinetic energy is equal to the final (top of loop) kinetic energy and it's Gravitational potential energy. The formula is : 1/2mv^2 = mgh + 1/2mv^2 divide by m since it is in all terms yields
