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

To determine the mass of the vehicle, we can use the formula for kinetic energy:

Kinetic energy (KE) = (1/2) * mass * velocity^2

Given that the kinetic energy is 25000J and the velocity is 5 m/s, we can rearrange the formula to solve for mass:

mass = (2 * KE) / (velocity^2)

Substituting the known values into the formula, we have:

mass = (2 * 25000J) / (5^2 m/s^2)
mass = 10000 kg

Therefore, the mass of the vehicle is 10000 kg.

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.
