in 1.85 s, it has moved -7.91 cm
... find the average velocity ... distance / time
the final velocity is ... (2 * average) - initial
acceleration is ... (final velocity - initial velocity) / time
An object moving with uniform acceleration has a velocity of 10.0 cm/s in the positive x-direction when its x-coordinate is 2.91 cm. If its x-coordinate 1.85 s later is −5.00 cm, what is its acceleration?
