What is the vertical component of its velocity at launch?

What is the horizontal component of its velocity at launch?

1) Horizontal velocity = 20 x cos 53 degrees = 12.0 m/s
 Vertical velocity = 20 x sin 53 deg = 16.0 m/s

2) Horizontal velocity = 10 x cos 68 = 3.75 m/s
Vertical velocity = 10 x sin 68 = 9.3 m/s
