Answer 1

what's the question?

Answer 2

I wish i could
I'll let nincompoop do it.

Answer 3

You could just go ahead and post the question. Many people here can help.

Answer 4

And what is the question?

Answer 5

The message you sent:
question is which statement is true
ball's velocity is:
ball's velocity is constant
velocity can't be measured
velocity at t=3 is zero
none of the above

Answer 6

The ball's velocity is NOT constant. The horizontal component of the velocity is constant but the vertical component is not and therefore the overall velocity is not constant.

Answer 7

I do not see any question

Answer 8

The vertical component of the velocity can be calculated from the graph but the horizontal component cannot be calculated because we don't know how far the ball traveled horizontally in the 6+ seconds. So the velocity can't be calculated.

The vertical component of the velocity at t = 3 is zero but not the horizontal component and so the overall velocity is not zero at t = 3 seconds.

Answer 9

do you need an explanation about
displacement, velocity, acceleration and their relationship with time?

Answer 10

Hey, why did you delete the link to the graph? I may have to revisit my answers. For some reason when I saw a parabola I assumed it was a projectile launched into the air which takes the shape of a parabola.

Answer 11

If you post the link back and the full question I will try to answer it.

Answer 12

review the attachments I uploaded
make sure you try your best, there are sample problems to make clear of the concepts
if you still need help even after that, you can ask for a better clarification

Answer 13

If the question says the object was tossed vertically up in the air and the graph shows the height of the object with respect to time then my answer will be different.

Answer 14

I attached 2 files look at them
