The rate of deceleration when a car goes from 90km/h to 0 in 6 seconds is 4.16m/s².

HOW TO CALCULATE DECELERATION?

The rate of deceleration can be calculated by using the following formula:

d = v - u/t

Where;

  • d = deceleration (m/s²)
  • v = final velocity = 90km/h = 25m/s
  • u = initial velocity = 0km/h = 0
  • t = time (s)

d = 25 - 0/6

d = 4.16m/s²

Therefore, the rate of deceleration when a car goes from 90km/h to 0 in 6 seconds is 4.16m/s².
