Question

A body moving with uniform acceleration has
a velocity of 8.95 cm/s when its x coordinate
is 2.76 cm.
If its x coordinate 2.99 s later is −6.18 cm,
what is the x-component of its acceleration?
Answer in units of cm/s2

Answer 1

You should use the kinematic equation,
\[x=x_0+v_0t+\frac{1}{2}at^2\]
Do you know how to apply?

Answer 2

Just solve for a?

Answer 3

And t, you should have a system of equations with two variables.

Answer 4

But t is 2.99 so don't I just plug in that?

Answer 5

Sorry, t is given. XD

Answer 6

Ha no problem :)

Answer 7

Only to check, my solution is -7.90 cm/s^2.

Answer 8

so is mine well, -7.9866

Answer 9

Perfect! ;)

Answer 10

lol thank you
