Math Problem Statement

A shell was fired with a velocity launch vector v. Find the launch components. Round your answer to the nearest hundredth.

Solution

We need to calculate the horizontal and vertical components of the launch velocity vv, given that:

  • v=708m/sv = 708 \, \text{m/s} (magnitude of the velocity),
  • θ=36\theta = 36^\circ (launch angle).

The formulas for the components are:

vx=vcos(θ)andvy=vsin(θ)v_x = v \cdot \cos(\theta) \quad \text{and} \quad v_y = v \cdot \sin(\theta)

Step 1: Calculate vxv_x (horizontal component)

vx=708cos(36)v_x = 708 \cdot \cos(36^\circ)

Using cos(36)0.809\cos(36^\circ) \approx 0.809:

vx=7080.809572.77m/sv_x = 708 \cdot 0.809 \approx 572.77 \, \text{m/s}

Step 2: Calculate vyv_y (vertical component)

vy=708sin(36)v_y = 708 \cdot \sin(36^\circ)

Using sin(36)0.587\sin(36^\circ) \approx 0.587:

vy=7080.587415.56m/sv_y = 708 \cdot 0.587 \approx 415.56 \, \text{m/s}

Final Results:

  • vx=572.77m/sv_x = 572.77 \, \text{m/s} (horizontal component),
  • vy=415.56m/sv_y = 415.56 \, \text{m/s} (vertical component).

Tip:

In projectile motion, the horizontal component of velocity remains constant, while the vertical component changes due to gravitational acceleration.
