### Problem Statement
A 0.322 kg particle moves in an xy plane according to the equations:
\[ x(t) = -17.0 + 2.00t - 3.00t^3 \]
\[ y(t) = 17.0 + 4.00t - 8.00t^2 \]
with \( x \) and \( y \) in meters and \( t \) in seconds. 

At \( t = 1.05 \) s, what are:
#### (a) The magnitude of the net force on the particle
#### (b) The angle (within the -180°, 180° interval relative to the positive direction of the x-axis) of the net force on the particle
#### (c) The angle of the particle's direction of travel

### Answer Fields
#### (a)
- **Number:**
  - **Units:** [Unit Selector]

#### (b)
