# How fast would would a car be propelled on this capacitor

Lets keep this simple.

I have a 3000 lb car
I have one of these:

Assuming a perfect state, How many of these would it take to propel the car to 50 mph ?
Assuming a perfect state, How fast would this propel the car assuming full discharge ?

four of them could hold as much energy as a 3000 lb car moving at 53 mph

The relevant energy equation is

½CV²  =  ½mv²       with V for voltage    and   v for velocity.

thank you

they are a grand each,

I would want to drive with enough storage half of the capacitors would hold enough power to pretty much accelerate.

that would mean I would need 8 one thousand dollar each capacitors.

Little too pricey for a 3k lb car.
