A mechanic replaces a worn out engine of a car with a new, more efficient. The old engine had a useful output power 52kW and and efficiency of 25%. The new engine has an efficiency of 30%. Calculate the useful output power of the new engine.
You can assume that the input power of both engine is the same

its okay

Explain

i really do not know

show the diagram then i will answer

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
