A projectile is launched with V0 = 7.6 m/s and initial angle = 1.27 radians above the horizontal. What is the initial horizontal component of the projectile velocity in miles per hour?

Respuesta :

Answer:

The horizontal component is  [tex]v_h = 1.7096 \ m/s[/tex]

Explanation:

A diagram illustrating the projection is  shown on the first uploaded image  (from  IB Maths Resources from British international school Phuket )

From the question we are told that  

    The initial velocity is  [tex]v_o = 7.6 \ m/s[/tex]

      The angle of projection is  [tex]\theta = 1.27 \ rad = 72.77^o[/tex]

The  horizontal component of this  projectile  velocity is  mathematically represented as

          [tex]v_h = v_o * cos (\theta )[/tex]

substituting values  

         [tex]v_h = 7.6 * cos (72.77 )[/tex]

        [tex]v_h = 1.7096 \ m/s[/tex]
