Question

A runner incregses

her speed from 3.1
m/s to 3.5 m/s
during the last 15
seconds of her run.
What was her
acceleration during
her big push to the
finish?

Answer 1

a = 0.027 m/s²

Explanation:

a = v₁ - v₀ / t

v₁ = 3.5

v₂ = 3.1

t = 15

then

a = (3.5 - 3.1) / 15

a = 0.4 / 15

a = 0.027 m/s²
