A block of mass m = 4 kg is dragged 2 m along a horizontal surface by a force F = 30 N acting at `53^(@)` to the horizontal. The initial speed is `3 m//s and mu_(k) = 1//8`.
Find the change in kinetic energy of the block

Explanation

To find the change in kinetic energy of the block, we will follow these steps:

### Step 1: Identify the Given Values
- Mass of the block, \( m = 4 \, \text{kg} \)
- Distance dragged, \( d = 2 \, \text{m} \)
- Applied force, \( F = 30 \, \text{N} \)
- Angle of applied force, \( \theta = 53^\circ \)
- Initial speed, \( u = 3 \, \text{m/s} \)
