Math Problem Statement

Find the components of vtot along the x and y axes in the figure below, where 𝜃 = 25.0° and vtot = 7.28 m/s

Find the components of vtot along the x and y axes in the figure below, where 𝜃 = 25.0° and vtot = 7.28 m/s.

Solution

To solve for the components of vtotv_{\text{tot}} along the x and y axes, we can break down the total velocity vtotv_{\text{tot}} into its horizontal (vxv_x) and vertical (vyv_y) components using trigonometry.

Given:

  • vtot=7.28m/sv_{\text{tot}} = 7.28 \, \text{m/s}
  • θ=25.0\theta = 25.0^\circ (angle with respect to the x-axis)

Steps:

  1. The component of the velocity along the x-axis (vxv_x) is calculated as: vx=vtotcos(θ)v_x = v_{\text{tot}} \cdot \cos(\theta)

  2. The component of the velocity along the y-axis (vyv_y) is calculated as: vy=vtotsin(θ)v_y = v_{\text{tot}} \cdot \sin(\theta)

Let me calculate the values for you.The components of the total velocity vtot=7.28m/sv_{\text{tot}} = 7.28 \, \text{m/s} are:

  • vx=6.60m/sv_x = 6.60 \, \text{m/s} (along the x-axis)
  • vy=3.08m/sv_y = 3.08 \, \text{m/s} (along the y-axis)

Tip: Always ensure the angle is referenced correctly (from the horizontal or vertical) when breaking vectors into components.
