Arabbit runs across a parking lot on which a set of coordinate axis has strangely enough been drawn on coordinate system. the rabbit's path is such that the component of its position with respect to an origin of coordinate are given by the function of time by x=-0.31t^2+7.2t+28 and y=0.22t^2-9.1t+30. the rabbit's position vector r is r(t) =x(t) i+y(t) j. what are the magnitude and direction of the rabbit's position vector at t=15s

the answer is b

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.
