The time taken can be found by using the formula

t =  \frac{d}{v}  \\

d is the distance

v is the velocity

From the question we have

t =  \frac{20}{4}  \\

We have the final answer as

2. A Formula One race car speeds up from rest to 27.8 m/s in a distance of 25 meters.
Nadya [2.5K]

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

God is with you!!!
