The horse is galloping at 13 m/s. Five seconds later, after climbing the hill, the horse is moving at 5.5 m/s. Find the acceleration that describes this change in velocity.

MUST SHOW WORK TO RECEIVE BRAINLIEST!!

i think its

answer: a) y=-8x+5

a) m= -8

b) m= -2

c) m= 7

d) m= 6

i guess it’s a and b

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.
