Question
The figure shows an initially stationary block of mass \( m \) on a floor. A force of magnitude \( 0.500mg \) is then applied at an upward angle \( \theta = 20^\circ \). What is the magnitude of the acceleration of the block across the floor if (a) \( \mu_s = 0.620 \) and \( \mu_k = 0.520 \) and (b) \( \mu_s = 0.400 \) and \( \mu_k = 0.330 \)?

**Diagram Explanation:**
- The diagram depicts a block on a surface. 
- A force \( \vec{F} \) is applied at an angle \( \theta \) relative to the horizontal axis \( x \).
- The angle \( \theta \) specified is \( 20^\circ \).
- The coordinate system is shown with \( x \) and \( y \) axes.

**Questions:**

(a) Determine the magnitude of acceleration for \( \mu_s = 0.620 \) and \( \mu_k = 0.520 \).
