Math Problem Statement

A man is pulling on a rope with a force of 85 N directed at an angle of 51◦ to the horizontal. What is the x-component of this force? Answer in units of N. 005 (part 2 of 2) 10.0 points What is the y-component of this force? Answer in units of N

Solution

To find the x- and y-components of the force, we’ll use trigonometric functions based on the given angle.

Given:

  • Force, F=85NF = 85 \, \text{N}
  • Angle to the horizontal, θ=51\theta = 51^\circ

X-Component of the Force

The x-component (horizontal component) of the force can be found using: Fx=Fcos(θ)F_x = F \cdot \cos(\theta) Fx=85cos(51)F_x = 85 \cdot \cos(51^\circ)

Calculating this, we get: Fx850.629353.49NF_x \approx 85 \cdot 0.6293 \approx 53.49 \, \text{N}

Y-Component of the Force

The y-component (vertical component) of the force can be found using: Fy=Fsin(θ)F_y = F \cdot \sin(\theta) Fy=85sin(51)F_y = 85 \cdot \sin(51^\circ)

Calculating this, we get: Fy850.777166.05NF_y \approx 85 \cdot 0.7771 \approx 66.05 \, \text{N}

Answers

  1. X-component: Fx53.49NF_x \approx 53.49 \, \text{N}
  2. Y-component: Fy66.05NF_y \approx 66.05 \, \text{N}
