Questions & Step-by-Step Solutions

If a force of 10 N is applied at an angle of 30 degrees to the horizontal, what is the horizontal component of the force?
  • Step 1: Understand that we have a force of 10 N applied at an angle of 30 degrees.
  • Step 2: Recognize that we need to find the horizontal component of this force.
  • Step 3: Use the cosine function because we are looking for the horizontal part of the force.
  • Step 4: Write the formula for the horizontal component: Horizontal Component = Force * cos(angle).
  • Step 5: Plug in the values: Horizontal Component = 10 N * cos(30 degrees).
  • Step 6: Calculate cos(30 degrees). The value of cos(30 degrees) is approximately 0.866.
  • Step 7: Multiply 10 N by 0.866: 10 N * 0.866 = 8.66 N.
  • Step 8: Conclude that the horizontal component of the force is 8.66 N.
  • Vector Resolution – The process of breaking down a force into its horizontal and vertical components using trigonometric functions.
  • Trigonometric Functions – Understanding how to apply cosine to find the horizontal component of a force at an angle.
