The rocket sled has a mass of 4 Mg and travels from rest along the horizontal track for which the coefficient of kinetic friction is μk = 0.20. If the engine provides a constant thrust T = 150 kN, determine the power output of the engine as a function of time. Neglect the loss of fuel mass and air resistance.
