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 Webapparent weight depends on the speed, but actual weight is constant. 2) Normal force from the seat points downwards TRUE. As the centrifugal force directed is greater than weight directed downwards, normal reaction is directed downwards. 3) The magnitude of normal force depends on how fast the person is moving TRUE.
