I have tried this one multiple times and got the following answers: 1.24E13, 1.24E14, 2.84E27, 5.67E26. I can't get this practice problem correct. Thank you for your help

Electric charge q=-4.1 mC and mass m=3.1×10−6 kg moves with a speed v=9 km/s along the electric field (with it or against it). What is the speed of the charge after the charge travels through a potential difference AV=-3 kV. -6 Express your answer in km/s, rounded to three places after the decimal.

What is the value?

a) A typical small passenger electric vehicle has a range of 200 km on an electric charge of 33 kWh. Convert this number into J/km (Joules per kilometer traveled). b) A comparably sized gasoline powered vehicle to (a) is rated as 25 miles per gallon. Convert this number into J/km (Joules per kilometer traveled). c) If gasoline costs $10.00 per gallon, and electricity $0.30 per kWh what is the difference in the cost of fuel per kilometer travelled between the electric vehicle in (a) and the gasoline powered vehicle in (b)? d) Surveys of EV owners show that they charge at home 70% of the time. Let us assume that for the remaining 30% they charge at a 60 kW rated "fast-charge” station. If patterns of travel remain the same, but we swap all our gasoline vehicles for electric vehicles, what is the ratio between installation of fast charging stations to gasoline pumps retired. e) The Chicago Transit Authority has about 2700 buses that travel a total of 240,000 miles daily. A typical bus…
