 ball is thrown at 30 m/s at an angle of 33° above the horizontal.  How high will it go?

To determine the maximum height the ball will reach, we can break down its initial velocity into vertical and horizontal components and then focus on the vertical motion.

### Step-by-Step Solution

1. **Calculate the vertical component of the initial velocity:**
   Given:
   - Initial velocity \( v = 30 \, \text{m/s} \)
   - Angle of projection \( \theta = 33^\circ \)

   The vertical component of the velocity \( v_y \) is:
   \[
   v_y = v \sin \theta = 30 \sin(33^\circ)
   \]
   
   Calculating this:
   \[
   v_y \approx 30 \times 0.5446 = 16.338 \, \text{m/s}
   \]

2. **Calculate the maximum height \( h \):**
   At the highest point, the vertical velocity becomes zero due to gravity. Using the kinematic equation:
   \[
   v_y^2 = u_y^2 - 2gh
   \]
   where:
   - \( v_y = 0 \, \text{m/s} \) (final vertical velocity at the maximum height)
   - \( u_y = 16.338 \, \text{m/s} \) (initial vertical velocity)
   - \( g = 9.8 \, \text{m/s}^2 \) (acceleration due to gravity)
   
   Rearranging for \( h \):
   \[
   h = \frac{u_y^2}{2g} = \frac{(16.338)^2}{2 \times 9.8}
   \]

   Calculating this:
   \[
   h = \frac{267.001}{19.6} \approx 13.62 \, \text{meters}
   \]

### Final Answer:
The maximum height the ball will reach is approximately **13.62 meters**.
