Answer:

20 m/s

Explanation:

The vertical component of the velocity of the ball is equal to the length of the perpendicular of a triangle such that it makes an angle of 30 degrees from the base and the length of the hypotenuse is 40 m/s. Sin(∅)*hypotenuse is the length of the perpendicular.

Vertical component of velocity is given by 40Sin(30°)=20
