A force of 40 N acts at 30^circ to the x-axis. Its x- and y-components are:

  1. Fx = 20 N, Fy = 34.6 N
  2. Fx = 40 N, Fy = 40 N
  3. Fx = 17.3 N, Fy = 10 N
  4. Fx = 34.6 N, Fy = 20 N
Answer

D) Fx = 34.6 N, Fy = 20 N

Fx = Fcostheta, Fy = Fsintheta: Fx = 34.6 N, Fy = 20 N. SLO P-11-B-01 · Understanding
