Question

The speed, v, of a vehicle in relation to its stopping distance, d, is represented by the equation v =3.57√d. What is the equation for stopping distance in terms of the vehicle’s speed?

hint Hint:

Rearrange the equation.

The correct answer is: 12.7449

Complete step by step solution:
Here, given equation is $v equals 3.57 square root of d$
Where, v is the speed of the vehicle and d is the stopping distance.
On squaring the equation, $v squared equals left parenthesis 3.57 square root of d right parenthesis squared$
$table attributes columnspacing 1em end attributes row cell space space not stretchy rightwards double arrow v squared equals 12.7449 d end cell row cell not stretchy rightwards double arrow d equals fraction numerator v squared over denominator 12.7449 end fraction end cell end table$
Now we have the equation for stopping distance in terms of the vehicle’s speed

The suspension cables from the Golden gate bridge’s towers are farther above the roadway near the towers and closer to the roadway near the middle of the bridge. You can figure out your distance from middle of the bridge, x, in feet, and height of the suspension cable, y, in feet, at your position by using the equation x = $fraction numerator square root of y to the power of negative 220 end exponent end root over denominator 0.010583 end fraction$ About how far is the cable from roadway when you are 200 ft from middle of the bridge
