What is the vertical component of its velocity at launch?

What is the horizontal component of its velocity at launch?

2.) What are the horizontal and vertical components of a 10 unit vector that is oriented 68° above the horizontal?

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

There are major differences in the metabolism of morphine and the illegal drug heroin. Morphine mostly produces its CNS effects through m-receptors, and at k- and d-receptors. Heroin has a slight affinity for opiate receptors. Most of its actions are due to metabolism to active metabolites (6-acetylmorphine, morphine, and morphine-6-glucuronide).
