A student of weight 643 N rides a steadily rotating Ferris wheel (the student sits upright). At the highest point, the magnitude of the normal force F→N on the student from the seat is 566 N. (a) What is the magnitude of F→N at the lowest point? If the wheel's speed is doubled, what is the magnitude FN at the (b) highest and (c) lowest point?

a) 720N

Explanation:

Centrifugal force pushing student upwards at the top Fc = (643 - 566)N = 77N

At the bottom, an equal centrifugal force Fb acts downwards on the student giving a total of :

Fc + 643 = 77 + 643 = 720N

b) The centrifugal force is quadrupled when speed is doubled ,therefore, the total force at the top = 643 - (4× 77)

= (643 - 308)N = 335N

c ) The total force at the top when the centrifugal force is quadrupled = 643 + (4×77)

= (643 + 308 )N = 951 N

speed

ratio of distance traveled to time interval

net force

vector sum of forces on object

object

source of diverging light rays either luminous or illuminated

don't remove my answer im trying my best to answer them

explanation:

b.transmitters send radio waves, and receivers capture radio waves.
