Vertical component: **23 m/s**

Horizontal component: **50. m/s**

#### Explanation:

For a given launch angle *vertical* and *horizontal components* of the initial velocity can be written as

In your case, the two components of the initial speed will be

and

Both values are rounded to two sig figs, the number of sig figs you gave for the arrow's initial velocity.
