Newton's law.. tension!?

Question

A gymnast of mass 70.0 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.

A) Calculate the tension T in the rope if the gymnast hangs motionless on the rope.
Express your answer in newtons.

B) Calculate the tension T in the rope if the gymnast climbs the rope at a constant rate.
Express your answer in newtons.

C) Calculate the tension T in the rope if the gymnast climbs up the rope with an upward acceleration of magnitude 1.30 m/s^2.
Express your answer in newtons.

D) Calculate the tension T in the rope if the gymnast slides down the rope with a downward acceleration of magnitude 1.30 m/s^2.
Express your answer in newtons.

Answer 1

F=m*a
there is the presence of gravity so A and B are both
70*9.81

C)F=70*(9.81+1.3)

D)F=70*(9.81-1.3)
