Question

If your car is going 19 m/s at the beginning of the block (250 meters long), and your acceleration is 3.9

m/s?, how fast are you going at the end of the block?

Answer 1

48 m/s

Step-by-step explanation:

Given:

Δx = 250 m

v₀ = 19 m/s

a = 3.9 m/s²

Find: v

v² = v₀² + 2aΔx

v² = (19 m/s)² + 2 (3.9 m/s²) (250 m)

v ≈ 48 m/s
