Calculation of Resultant Force of Two Forces

Two forces with magnitudes 50 N and 30 N are acting at an angle of 60 degrees. To determine the resultant force of these two forces, use the following steps:

Step 1: Determine the x- and y-components of each force.


  • 50 N force:

    • x-component: 50 cos(60) = 25 N
    • y-component: 50 sin(60) = 43.3 N



  • 30 N force:

    • x-component: 30 cos(60) = 15 N
    • y-component: 30 sin(60) = 25.98 N




Step 2: Add the x- and y-components separately.


  • x-components: 25 N + 15 N = 40 N
  • y-components: 43.3 N + 25.98 N = 69.28 N


Step 3: Use the Pythagorean theorem to find the magnitude of the resultant force.

Resultant force = sqrt((40 N)^2 + (69.28 N)^2) = 80.1 N

Step 4: Use trigonometry to find the direction of the resultant force.

tan(theta) = 69.28 N / 40 N
theta = 60.2 degrees

Therefore, the resultant force of the two forces with magnitudes 50 N and 30 N acting at an angle of 60 degrees is 80.1 N at an angle of 60.2 degrees.
