Math Problem Statement

Calculate the x and y components of the following force: F = 131 N, θ = 70.8°. What is the value of the x component of the force? Include the minus sign if the x component is acting in the negative direction.

Solution

To calculate the x and y components of the given force:

Given:

  • F = 131 N (magnitude of the force)
  • θ = 70.8° (angle with the positive x-axis)

Formula:

  1. x-component: Fx=Fcos(θ)F_x = F \cdot \cos(\theta)
  2. y-component: Fy=Fsin(θ)F_y = F \cdot \sin(\theta)

Calculation:

x-component:

Fx=131cos(70.8)F_x = 131 \cdot \cos(70.8^\circ)

y-component:

Fy=131sin(70.8)F_y = 131 \cdot \sin(70.8^\circ)

I will compute the results now. math

Given values

F = 131 # Force magnitude in N theta_deg = 70.8 # Angle in degrees

Convert angle to radians

theta_rad = math.radians(theta_deg)

Calculate x and y components

Fx = F * math.cos(theta_rad) Fy = F * math.sin(theta_rad)

Fx, Fy### Results:

  1. x-component: Fx=43.1NF_x = 43.1 \, \text{N} (rounded to one decimal place)
  2. y-component: Fy=123.7NF_y = 123.7 \, \text{N} (rounded to one decimal place)

The x-component is positive because the force is acting in the positive x-direction.
