The force vector A has components A subscript x end subscript equals 5 N, A subscript Y end subscript equals negative 3 N. The force vector B has components B subscript x end subscript equals 5 N, B subscript y end subscript equals 4 N. What are the components of the resultant force vector C = A + B?


C subscript x end subscript equals 10 N, C subscript y end subscript equals 7 N


C subscript x end subscript equals 2 N, C subscript y end subscript equals 9 N


C subscript x end subscripit equals 0 N, C subscript y end subscript equals negative 7 N


C subscript x end subscript equals 10 N, C subscript y end subscript equals 1 N

Respuesta :

I believe that it is the third one(C subscript x end subscripit equals 0 N, C subscript y end subscript equals negative 7 N)   and please tell me if i mright or wrong please mark brainliest

A has components A subscript x end subscript equals 5 N, A subscript Y end subscript equals negative 3 N.

A = Ax + Ay = 5x + 3y

B has components B subscript x end subscript equals 5 N, B subscript y end subscript equals 4 N.

B = Bx + By = 5x + 4y


C = A + B

= Ax + Ay + Bx +By

= 5x + 3y + 5x + 4y

= 10x + 7y


So C = Cx + Cy where Cx = 10N and Cy = 7N

The answer is C subscript x end subscript equals 10 N, C subscript y end subscript equals 7 N.
