Thanks! Seems like the question was not complete in this case, as no mass was given

What about "The linear energy change is equal to: Ke linear change =(1/2)mv1^2−(1/2)mv2^2"?? Please understand that I am working with limited information and this is what I found, Physics is not my expertise but I want to understand what I am missing in this problem...

Start velocity is 100 km/h, at 1.5g for 0.5 seconds the end velocity will be 73,52 km/h. So the energy can be calculated if the mass is present, but it is not given. Is there a way to calculate the regenerated energy with the given information?
