Question

**Understanding Power Requirements in Projectile Acceleration**

The problem presented involves calculating the power required to accelerate a projectile. Here is the scenario and query outlined:

1. **Initial Condition:**
- The power needed to accelerate a projectile from rest to its launch speed \( v \) in a time \( t \) is given as \( 51.4 \) watts (W).

2. **Problem Statement:**
- We need to determine how much power is required to accelerate the same projectile from rest to a launch speed of \( 2v \) in a time of \( \frac{1}{2} t \).

To solve this problem, one needs to understand the relationship between power, force, and acceleration. Specifically, we need to calculate how changing the final speed and the time over which this acceleration takes place affects the power required.

*Note: The problem does not include any graphs or diagrams, but understanding the mathematical relationships and principles involved is crucial for solving such problems efficiently.*
