Worked practice questions

The train slows from 30.0 km/h to a stop in 8.00 s. Its acceleration is about:

  1. +1.04 m/s squared
  2. -3.75 m/s squared
  3. -0.42 m/s squared
  4. -1.04 m/s squared
Show answer and solution

Correct answer: D. -1.04 m/s squared

1. Convert 30 km/h to m/s first. 2. The change divided by 8.00 s gives about -1.04. 3. The minus sign shows it opposes the motion. _Source: OpenStax College Physics for AP Courses 2e, Chapter 2, Kinematics (CC BY 4.0)._
