No idea how to do this.

An object moving with uniform acceleration has a velocity of 11.0 cm/s in the positive x-direction when its x-coordinate is 2.91 cm. If its x-coordinate 2.75 s later is −5.00 cm, what is its acceleration?

The answer is -10.1 cm/s squared but I don't know how to get to the answer. Any help would be great. Thanks.

As you know velocity=Δdisplacement/Δtime.
What do you know about constant acceleration definition?

Perhaps look at one of the SUVAT equation of motion.

You know the displacement s, the time t and the initial velocity v.

I'll let you decide which equation you need to solve for "a".
