A 79.0 kg person is being pulled away from a burning building as shown in the figure below. 15 T, -10' W (a) Calculate the tension (in N) in the first rope, T, , if the person is momentarily motionless. (Enter the magnitude only.) (b) Calculate the tension (in N) in the second rope, TOif the person is momentarily motionless. (Enter the magnitude only.)A man is standing on a scale inside an elevator. As the elevator starts to go up with an acceleration a, the scale reads 830 N. The mass of the man is m - 70 kg. (a) Which of the free body diagrams below displays all the forces acting on the man with the correct relative magnitudes and directions? N N ma N W W W O O N\fhere N is Net force . Net force means Yme Normal force - Fa and this net force ( N )will be Fa = ma - force due to less than weight of the acceleration person ( my ), my mass of person Correct answer : and diagram
