A vehicle expends an energy of 25000J while moving at a constant speed of 5 ms.what is the mass of vehicle?

I have no idea. At constant speed propulsion force = drag force and mass is not part of the problem.
Kinetic Energy = (1/2)*m*v^2 maybe?
25,000 = 0.5*m*5^2
Solve for m then.
25,000 = 0.5*m*5^2
Solve for m then.
