A body moving with uniform acceleration has a velocity of 11.1cm/s when it's coordinate is 3.59cm. If it's x coordinate 2.48sec later is -3.58cm, what is the x-component of it's acceleration. Answer in units of cm/s^2

1 answer

counting from t=0 when x=3.59,

x(t) = 3.59 + 11t + 1/2 at^2
-3.58 = 3.59 + 11*2.48 + 1/2 a * 2.48^2
a = -11.2 cm/s^2
