A gymnast of mass 64.0{\rm kg} hangs from a vertical rope attached to the ceiling. You can ignore the weight of the rope and assume that the rope does not stretch. Use the value 9.81 {\rm m/s^2} for the acceleration of gravity. Calculate the tension T in the rope if the gymnast hangs motionless on the rope. Express your answer in newtons. Calculate the tension T in the rope if the gymnast climbs the rope at a constant rate. Express your answer in newtons.
