A supertanker (mass = 1.57E+8 kg) is moving with a constant velocity. Its engines generate a forward thrust of 7.47E+5 N. Determine the magnitude of the resistive force exerted on the tanker by the water.

7.47×10^N is correct, but I need to know how

  • physics -

    constant velocity (not accelerating), means the the thrust equals the resistive force

  • physics -

    M = 1.57*10^8 kg.
    Ft = 7.47*10^5 N.
    Fr = ?.

    Ft-Fr = M*a.
    Ft-Fr = M*0,
    Ft-Fr = 0,
    Fr = Ft = 7.47*10^5 N.
