A motor pulls a block of mass \(M\) up a frictionless ramp inclined at an angle \(\theta\) above the horizontal. The block moves up the ramp at a constant speed \(v\), and the motor delivers a power \(P_0\) to the block. The motor then pulls a different block of mass \(2M\) up the same ramp at a constant speed \(3v\). What is the power delivered by the motor to the second block in terms of \(P_0\)?
