Math Problem Statement

Find the horizontal (F_H) and vertical (F_V) components of a force of 9 N at an angle of 32° to the horizontal. Give your answers correct to 1 decimal place.

Solution

The question is asking for the horizontal (FHF_H) and vertical (FVF_V) components of a force of 9 N at an angle of 32° to the horizontal. To solve this, we can use trigonometric functions:

  • The horizontal component (FHF_H) is found using FH=Fcos(θ)F_H = F \cdot \cos(\theta).
  • The vertical component (FVF_V) is found using FV=Fsin(θ)F_V = F \cdot \sin(\theta).

Where:

  • F=9NF = 9 \, \text{N} (the magnitude of the force),
  • θ=32\theta = 32^\circ (the angle with the horizontal).

Now, let's compute:

  1. FH=9cos(32)F_H = 9 \cdot \cos(32^\circ)
  2. FV=9sin(32)F_V = 9 \cdot \sin(32^\circ)

Calculating these:

  • FH90.848=7.63NF_H \approx 9 \cdot 0.848 = 7.63 \, \text{N} (to 1 decimal place).
  • FV90.530=4.77NF_V \approx 9 \cdot 0.530 = 4.77 \, \text{N} (to 1 decimal place).

So:

  • FH=7.6NF_H = 7.6 \, \text{N}
  • FV=4.8NF_V = 4.8 \, \text{N}
