Two points are located on a rigid wheel that is rotating withdecreasing angular velocity about a fixed axis. point a islocated on the rim of the wheel and point b is halfway between therim and the axis. which one of the following statements concerningthis situation is true?
both points have the same centripetal acceleration.
both points have the same tangential acceleration.
the angular velocity at point a is greater than that of pointb.
both points have the same instantaneous angular velocity.
each second, point a turns through a greater angle than pointb.

step-by-step 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.
