Question

Vx is the velocity of a particle moving along the x-axis as shown. If x = 2.0 m at t = 1.0 s,
what is the position of the particle at t = 6.0 s?

Answer 1

you need to figure out whether the acceleration is constant or not before we can help you

Answer 2

the graph is up, can that help

Answer 3

okay so heres what you should do first. Make an Acceleration vs. Time graph, do you know how to get acceleration from a velocity graph?

Answer 4

No , I dont but I though you had to find the area of the triangles on the graph than add them up?

Answer 5

I need help with explaining that.

Answer 6

you are close. The area under a velocity graph doesn't give you acceleration, instead it gives you the displacement

Answer 7

however, remember displacement is not the same as position, which is why you need to find the acceleration graph first beacause the acceleration changes throughout the movement of the object

Answer 8

than can you please tell me how to do the displacement, I am really sorry that is what my teacher did to get the answer but i dont know how. Sorry for the trouble.

Answer 9

ok so like i said earlier the area under a velocity graph gives you the displacement. so you need to find the area of the triangles and add them together

Answer 10

theres a khan academy video on how to do this, you should watch it

Answer 11

Alright thanks
