Finding quadratic equation

Question

The braking distance of a car travelling at 100km/h is 40 metres. The formula for braking distance (d) in metres is d=kx2 where k is constant and x is speed in km/h.  a) Find the value of k

Patrick B. · Accepted Answer

40 = k*100^240/10000 = k4/1000 = k1/250 = k
