Answer:

-3.03 m/s²

Explanation:

v² = v₀² + 2a(x − x₀)

where v is the final velocity,

v₀ is the initial velocity,

a is the acceleration,

x is the final position,

and x₀ is the initial position.

Given:

v = 0 m/s

v₀ = 25 m/s

x = 103 m

x₀ = 0 m

Find: a

v² = v₀² + 2a(x − x₀)

(0 m/s)² = (25 m/s)² + 2a (103 m − 0 m)

a = -3.03 m/s²

Round as needed.
