Complete question

A cannon with a muzzle velocity of 500. meters per second fires a cannonball at an angle of 30.° above the horizontal. What is the vertical component of the cannonball's velocity as it leaves the cannon?

A   0.0 m/s

B    250. m/s

C   433 m/s

D    500. m/s

Answer:

The correct option is  C

Explanation:

From the question we are told that

   The velocity is  [tex]v = 500 \ m/s[/tex]

    The angle is  [tex]\theta = 30^o[/tex]

   

Generally the vertical component of the canon ball is mathematically represented as  

          [tex]v_y = v * cos (30 )[/tex]

=>       [tex]v_y = 500 * cos (30 )[/tex]

=>       [tex]v_y = 433 \ m/s[/tex]

Answer:

250. m/s

Explanation:

It is vertical component so you do: 500mSin(30°) = 250m/s
