Question

An object increases its speed from rest to 35 m/s while traveling over a distance of

400 meters. Determine the acceleration of the object.

Answer 1

1.53 m/s²

Step-by-step explanation:

Given:

Δx = 400 m

v₀ = 0 m/s

v = 35 m/s

Find: a

v² = v₀² + 2aΔx

(35 m/s)² = (0 m/s)² + 2a (400 m)

a = 1.53 m/s²
