PLEASE HELP ME ASAP Quincy is monitoring the movement of a particle along the x-axis of an x-y plane. The velocity is negative, and the acceleration is positive. Which of the following describes what Quincy observes?

a. The particle is moving in a negative direction, and its speed is increasing.
b. The particle is moving in a positive direction, and its speed is increasing.
c. The particle is moving in a positive direction, and its speed is decreasing.
d. The particle is moving in a negative direction, and its speed is decreasing.

c. The particle is moving in a positive direction, and its speed is decreasing.

d. The particle is moving in the negative direction, and its speed is decreasing

Explanation:

this isn't the answer but they're the graphs

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.
