On Jupiter's icy moon Europa, the gravitational field strength is 1.30 N/kg. A robotic research probe of mass 85 kg is being hauled up a rough research ramp inclined at an angle of 25∘ 25^\circ\,25∘ to the horizontal at a constant speed.
The coefficient of friction between the probe and the ramp is μ=0.15\mu = 0.15μ=0.15. The hauling cable runs parallel to the surface of the ramp.
Calculate the tension T T\,T in the hauling cable.
