Answer:

3 m/s

Explanation:

Given:

a = 2 m/s²

Δx = 10 m

v = 7 m/s

Find: v₀

v² = v₀² + 2a (x − x₀)

(7 m/s)² = v₀² + 2 (2 m/s²) (10 m)

v₀ = 3 m/s

Ivahew [28]
<h3>Given, </h3>

Force,F = 4000 N

Area,a = 50 m²

<h3>We know that, </h3>

Pressure = Force/Area

★ Putting the values in the above formula,we get:

\sf \rightarrow \: pressure =  \dfrac{4000}{50}

\sf \rightarrow pressure = 80 \: N {m}^{ - 2}
