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.
