Figure 5-55 shows a man sitting in a bosun's chair that dangles from a mass-less rope, which runs over a massless, frictionless pulley and back down to the man's hand. The combined mass of man and chair is 103.0 kg. With what force magnitude must the man pull on the rope if he is to rise (a) with a constant velocity and (b) with an upward acceleration of `1.30" m"//"s"^(2)` ?

Explanation

(a) 505 N, (b) 572 N, ( c ) 0.01 kN, (d) 1.14 kN, (e) 1.01 kN, (f) 1.14 kN, (g) 2.02 kN, (h) 2.29 kN
