Aferris wheel has diameter of 10 m and makes one revolution in 8.0 seconds. a woman weighing 670 n is sitting on one of the benches attached at the rim of the wheel. what is the net force on this woman as she passes through the highest point of her motion?

208 N

Explanation:

The net force on the woman is equal to the centripetal force, which is given by

where

m is the mass of the woman

v is her speed

r is the radius of the wheel

here we have:

r = d/2 = 5 m is the radius of the wheel

is the mass of the woman (equal to her weight divided by the acceleration of gravity)

The wheel makes one revolution in t=8.0 s, so the speed is:

so now we can find the centripetal force:

are their multiple choices ?

explanation:

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
