Hello,

Can someone help explain the following problem? It is supposedly a "review" question but I really have no idea where to start. Thanks.

A force vector has a magnitude of 340 newtons (N) and points at an angle of 60.0° below the positivexaxis.

(a) What is the algebraic expression for thexscalar componentFx of the force vector? Express your answer in terms of the magnitudeFof the force vector and the angleθthat specifies the direction below the positivexaxis. Remember that scalar components can be positive or negative, depending on whether they point, respectively, along the positive or negative axis. (Answer using F forFand theta forθ.)

(b) What is thexscalar componentFx of the force vector?

(c) What is the algebraic expression for theyscalar componentFy of the force vector? Express your answer in terms of the magnitudeFof the force vector and the angleθthat specifies the direction below the positivexaxis. Remember that scalar components can be positive or negative, depending on whether they point, respectively, along the positive or negative axis. (Answer using F forFand theta forθ.)

(d) What is theyscalar componentFy of the force vector?

Any help would be appreciated and I am sure that if someone could explain parts a and b I could do c and d.

Thanks,
