Answer:

Correct answer:   a = 15.46 m/s²

Explanation:

The formula for accelerated movement with the given data is:

V² - V₀² = 2 · a · d     where the initial velocity  V₀ and the final V  

Since the initial velocity V₀ is zero, the formula is:

V² = 2 · a · d  => a = V² / (2 · d) = 27.8² / (2 · 25) = 772.84 / 50 = 15.46 m/s²

a = 15.46 m/s²
