Question

A car changes speed from 25 m/s to 10 m/s in 240 seconds. Describe its acceleration.​

Answer 1

Step-by-step explanation:

Acceleration is change in velocity over change in time:

a = Δv / Δt

a = (10 m/s - 25 m/s) / (240 s - 0 s)

a = -0.0625 m/s²

So the car decelerates at 0.0625 m/s².
