    Power concept related to gravity, constant speed, and air resistance

    Homework Statement An object weighting 100N is traveling vertically upward from the Earth in the absence of air resistance at a constant velocity of 5 m/s. What is the power required to keep the object in motion? Homework Equations P = ΔE/t and P = Fvcosθ The Attempt at a Solution...
