Two horizontal forces act on a

7.2kg

chopping block that can slide over a frictionless kitchen counter, which lies in an xy plane. One\ force is

vec(F)_(1)=(2.5N)hat(i)+(2.0N)hat(j)

. Find the acceleration of the chopping block in unit-vector notation when the other force is (a)\

vec(F)_(2)=(-2.5N)hat(i)+(-2.0N)hat(j)

, (b)

vec(F)_(2)=(-2.5N)hat(i)+(2.0N)hat(j)

, and

(c)vec(F)_(2)=(2.5N)hat(i)+(-2.0N)hat(j)

Two horizontal forces act on a 7.2kg chopping block that can slide over a frictionless kitchen counter, which lies in an xy plane. One force is F1=(2.5N)i^+(2.0N)j^. Find the acceleration of the chopping block in unit-vector notation when the other force is (a) F2=(2.5N)i^+(2.0N)j^, (b) F2=(2.5N)i^+(2.0N)j^, and (c) F2=(2.5N)i^+(2.0N)j^
