The "giant swing" at a county fair consists of a vertical central shaft with a number of horizontal arms attached at its upper end. each arm supports a seat suspended from a cable 5.00 m long, the upper end of the cable being fastened to the arm at a point 3.00 m from the central shaft. does the angle depend on the weight of the passenger for a given rate of revolution?

In the expression the mass is cancelled out and angle is independent of the weight of the person

Explanation:

Let the swing is rotating with constant angular speed

now due to rotation of swing the string will make some angle with the vertical

now we have

now we will have

here we know that

where

R = 3.00 m

L = 5.00 m

Now as we can see the above expression the mass is cancelled out and angle is independent of the weight of the person

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.
