Question

1. A car's speedometer reads 20 m/s after accelerating, from a standing start, for 25s. What
was the magnitude of its acceleration?​

Answer 1

Answer:

0.8 m/s²

Explanation:

Acceleration is the change in velocity over change in time.

a = Δv / Δt

a = (20 m/s − 0 m/s) / 25 s

a = 0.8 m/s²
