Hi pls give good explanation thank you

On a roller coaster, you round the top of a circular hump in the track of 5.0 m radius. You have a g-force meter with you and at the moment you're at the top it reads a vertical g-force of 0.00 (a) State your weight at that moment and justify the answer (to) Determine the magnitude of the normal force exerted on you by the seat at that moment and justify the answer (c) Determine your centripetal acceleration and justify the answer. (d) Calculate your speed at the top. (e) Assuming friction and air resistance are negligible, calculate your horizontal g-force at that moment. justify your
