2. A Formula One race car speeds up from rest to 27.8 m/s in a distance of 25 meters.

Determine the acceleration achieved by the car.

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

God is with you!
