In Problem, refer to Problem 51. Then find the stopping distance for each of the following speeds.

70 mph

Reference Problem 51

The number of feet that a car travels before stopping depends on the driver’s reaction time and the braking distance, as shown below. For one driver, the stopping distance d is given by the equation

where v is the velocity (speed) of the car. Find the stopping distance when the driver is traveling at 30 mph.
