The initial velocity of the ball is given as 36.0 m/s.
The horizontal component of velocity of ball is given as,
The ball is projected vertically, therefore, the angle made by ball is 90 degree.
Plug in the known values,
Therefore, the initial horizontal velocity of ball is 0 m/s.
The vertical component of velocity of ball is given as,
Plug in the known values,
Therefore, the initial vertical velocity of the ball is 36.0 m/s.
