Two horizontal forces act on a 2.0 kg chopping block that can slide over a frictionless kitchen counter, which lies in an xy plane. One force is F1 = (3.0N)i + (4.0N)i. Find the acceleration of the chopping block in unit-vector notation when the other force is

(a) F2 = (– 3.0 N)i + (– 4.0 N)j,

(b) F2 = (– 3.0 N)i + (4.0 N)i, and
