THE FORCES ARE ACTING UPON A 2.0KG OBJECT. FIND VALUES OF A_X AND A_Y.

Answer 1

ONE FACT, THE ACCELERATION VECTOR IS ALWAYS IN THE SAME DIRECTION AS THE NET FORCE. BUT MAGNITUDES MAY DIFFER.

Answer 2

that makes no sense.

Answer 3

Its true in this universe.

Answer 4

@timo86m can you please help me

Answer 5

or if you can @mathmale

Answer 6

Would you mind choosing just one problem on which to focus? Seeing all those different situations at once without knowing which one is important to you is a bit overwhelming.

Answer 7

free body diagram a, i need to solve for the acceleration in the x and y directions

Answer 8

I am familiar with this kind of problem. Before we start, tell me, please, in your own words, what you think we need to do in order to find those two accelerations.

Answer 9

When I attempted the problem I was using the sum of all forces in the x direction and then once I got that I was going to use F=ma and solve for a and that would be my acceleration in the x direction. But I did that and had double the acceleration than what the answer was suppose to be, which was in the back of my textbook (sometimes it is not always correct but I use it to have an idea of where my answer should be).

Answer 10

that sounds like a very good plan of attack and I'd like to compliment you on it.
would you mind taking another look at this problem and listing all the vertical force components?

The 3N downward force is obviously one of those.
What is the y-component of the 2.82N force?

Answer 11

I am unsure of what you are asking about the y-component of 2.82N?

Answer 12

the instructions for this problem ask you to decompose the vectors into their horizontal and vertical components. Have you experienced this before?

Answer 13

yes but not much.

Answer 14

2.82N is the normal force acting upon the object.

Answer 15

May I have a nickname by which to call you ? Are you, for example, Mickey or Mikhael?

That 2.82 N vector is not in the vertical direction, it points in the NorthWest direction. I will draw a picture to demo how to find its vertical comp.

Answer 16

My name is Mikaela, you can call me Mik if you do not want to type Mikaela lol.

Answer 17

The Normal Force is in the y- direction because the coordinate plane is tilted.
