Ok, I am trying to solve this very simple equation, but I encountered a conflict.

The question is a 1000kg car goes from 0m/s to 10m/s in 3 seconds. What is the work?

I know there are two work formulas I can use here.

The kinetic energy formula of 1/2mv^2

The work formula of Force x distance

If I use force x distance, using average velocity of 5m/s x time to get 15m distance, multiplied by the force of 1000kg, I get 15x10^4

But if I use kinetic energy formula, I get an answer of 5x10^4

When I checked my answers, the Kinetic energy formula yielded the correct answer, but I dont know why the force x distance formula didnt give me the same answer.

I know that both force x distance formula, and the kinetic energy formula is used for problems involving an object going a distance.

How come I cant get the same answer on these 2 different equations?
