A car accelerates uniformly from 18 km/h to 72 km/h in 5 s. What is the acceleration of the car?

  1. 10.8 m/s²
  2. 13.5 m/s²
  3. 6 m/s²
  4. 3 m/s²
Show answer and solution

Correct answer: D. 3 m/s²

1. Convert speeds: 18 km/h = 5 m/s, 72 km/h = 20 m/s. 2. Acceleration a = (v − u) / t = (20 − 5) / 5. 3. a = 15 / 5 = 3 m/s². _Source: RRB Group D CEN-02/2018 PYQ, Q.4._
