A racing car reaches a speed of 42 m/s. It then begins to decelerate, using its parachute and braking system, and comes to rest 5.5 s later. Find the rate of deceleration.

The rate of deceleration of a racing car that reaches a speed of 42m/s is 7.64m/s.

How to calculate deceleration?

Deceleration is the amount by which a speed or velocity decreases.

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

d = (v - u)/t

Where;

  • d = deceleration
  • v = final velocity
  • u = initial velocity
  • t = time

According to this question, a racing car reaches a speed of 42m/s. It then begins to decelerate, using its parachute and braking system, and comes to rest 5.5s later. The deceleration can be calculated as follows:

d = (42 - 0)/5.5

d = 42/5.5

d = 7.64m/s

Therefore, the rate of deceleration of a racing car that reaches a speed of 42 m/s is 7.64m/s.
