After an accident, police can determine how fast a car was traveling before the driver put on his breaks by using the equation In this equation,

s represents the speed in miles per hour, f represents the coefficient of friction, and d represents the length of the skid in feet. The coefficient of friction varies with road conditions. Suppose the coefficient of friction is 0.6.

a. Find the speed of a car that skids 25 feet.

b. If you were driving 35 miles per hour, how many feet would it take you to stop?

c. If the speed is doubled, will the skid be twice as long? Explain.
