Impulse = change in momentum
The car's momentum was (mass) x (speed)
Momentum = (2400 kg) x (20 m/s)
Momentum = 48,000 km-m/s
To completely stop the car, the impulse = -48,000 km-m/s .

If she has a choice and the wiring details are stated on the packaging, 
then Janelle should look for lights that are wired in parallel within the 
string, and she should avoid lights that are wired in series within the string.  
If a single light in a parallel string fails, then only that one goes out.  
The rest of the lights in the string continue to shimmer and glimmer.
If a single light in a series string fails, then ALL of the lights in that string 
go out, and it's a substantial engineering challenge to determine which light 
actually failed.
