Question

Velocity of a body is 20m/s making an angle of 30 degree with the horizontal the vertical component of velocity is

Answer 1

Answer:

10 m/s

Explanation:

Angle between them is 30°

velocity of the body is 20 m/s

therefore, it's vertical component will be,

20sin30°

=20×1/2

=10 m/s answer

hence, it's vertical component is 10 m/s

Answer 2

Answer:

17.32m/s ,10m/s

Explanation:

Angel between them is 30°

velocity of the body is 20m/s

therefore its vertical component is

= 20sin30°

=20×1/2

=10m/s

its horizontal component is

=20cos30°

=20×√3/2

=10×√3

=17.32m/s

* Note horizontal side will be always- sin

and vertical component will be- cos
