A golf ball is hit with an angle of elevation 30∘ and speed 20????????/????. Find the horizontal and vertical components of the velocity vector.

Respuesta :

Answer:

 Horizontal  [tex]u_x=10\sqrt{3}\ m/s[/tex]

Vertical [tex]u_y=10\ m/s[/tex]

Explanation:

Given that

Angle ,θ = 30°

Speed ,u= 20 m/s

The horizontal component ,ux= u cosθ

ux=20 cos 30° m/s

[tex]u_x=10\sqrt{3}\ m/s[/tex]

The vertical component ,uy= u sinθ

uy=20 sin 30° m/s

[tex]u_y=10\ m/s[/tex]

Therefore the components of golf ball will be

Horizontal  [tex]u_x=10\sqrt{3}\ m/s[/tex]

Vertical [tex]u_y=10\ m/s[/tex]
