A body moving with uniform acceleration has a velocity of 10.2 cm/s when its x coordinate is 3.73 cm.If its x coordinate 2.33 s later is −2.74 cm,what is the x-component of its acceleration?Answer in units of cm/s^2

a=(v - v.)/t
= ((x/t) - v. )/t
= ((-2.74/2.33) - 10.2) / 2.33
= ( -1.18-10.2)/2.33
= 4.88 cm/s**2
= 0.0488 m/s**2
