An object of mass 100 kg is released from rest from a boat into the water and allowed to sink. While gravity is pulling the object down, a buoyancy force of 1/40 times the weight of the object is pushing the object up (weight = mg). Assume that water resistance exerts a force on the object that is proportional to the velocity of the object, with proportionality constant 10 N-sec/m. Answer the following questions. (a) Find the force due to gravity. Use g = 9.81 m/sec^2. (b) Find the buoyancy force. (c) Express the air resistance force using the given information
