9. A driver of a car traveling at 15.0 m/s applies the brakes, causing a uniform acceleration of - 2.0 m/s2. How long does it take the car to accelerate to a final speed of 10.0 m/s? How far has the car moved during the braking period?
long will it take for the car

f=ma a/f/m a= 480/60 a = 8m/s/s that is quick wow

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
