Question

a car slows down from - 27.7 m/s to -10.9 m/s while undergoing a displacement of -105 m .what is its acceleration?

Answer 1

3.09 m/s²

Step-by-step explanation:

Given:

Δx = -105 m

v₀ = -27.7 m/s

v = -10.9 m/s

Find: a

v² = v₀² + 2aΔx

(-10.9 m/s)² = (-27.7 m/s)² + 2a (-105 m)

a = 3.09 m/s²
