Two horizontal forces act on a 9.9 kg chopping block that can slide over a frictionless kitchen counter, which lies in an xy plane. One force is 7₁ = (8.1 (8.1 N) N ) î + (4.4 + (4.4 N )ĵ. Find the acceleration of the chopping block in unit- vector notation when the other force is (a) F₂ = ( − 8.1 F2 N ) î + ( − 4.4 N )ĵ, (b) N ) î + (4.4 N )ĵ, and (c) F₂ = ( − 8.1 F₂ = (8.1 N ) î + ( − 4.4 N )ĵ.
