Deceleration also known as retardation or negative acceleration, is the acceleration acts in the opposite direction of motion and is responsible for reducing the velocity of a body. \[Deceleration(a)\: =\: \frac{Final\: velocity\: -\: Initial\: velocity}{Time}\] Retardation Factor Calculator. Retardation Factor R = 1 + r b k d / q. R = retardation factor.

Unfortunately I do not know what car retardation is, how to calculate it, or how to proceed from there to use it to calculate the distance. The question: A car, accelerating uniformly, reaches a speed of 30ms/1 from rest in 3 minutes.

asked Dec 1, 2017 in Class IX Science by ashu Premium ( 930 points) 0 votes Retardation Coefficient. The retardation coefficient expresses how much slower a contaminant moves than does the water itself. where R is the retardation coefficient, r b is the bulk density, k d is the sorption coefficient, and q is the porosity. Background. A simplified method of accounting for sorption is in common usage. In Eqn. 12.10b, λ = ln(2)/t 1/2 = 0.693/t 1/2, where t 1/2 is the half-life. It is becoming clear that such simple concepts as the retardation factor and a first-order rate constant are adequate for describing only simple contaminant problems.
