Question

A truck on the freeway accelerates from a velocity of 12m/s to a velocity of 28 m/s over a distance of 40.0 m. Calculate the acceleration of the truck

Answer 1

8 m/s²

Step-by-step explanation:

Given:

v₀ = 12 m/s

v = 28 m/s

Δx = 40.0 m

Find: a

v² = v₀² + 2a (x − x₀)

(28 m/s)² = (12 m/s)² + 2a (40.0 m)

a = 8 m/s²
