The braking distance Dv in meters for a certain car moving a

The braking distance D(v) (in meters) for a certain car moving at velocity v (in meters/second) is given by D(v) = v^2/26. The car\'s velocity B(t) (in meters/second) t seconds after starting is given by B (t) = 9t. Write a formula for the braking distance S(t) (in meters) after t seconds. It is not necessary to simplify. S (t) =

Solution

D(v) = v^2/26 ;

B(t) = 9t

Braking distance:substitute value of v = B(t)

S(t) = (9t)^2/26 = 81t^2/26 after t sec.
