Thecombined mass of man and chair is 95.0kg. With what force magnitude must theman pull on the rope if he is to rise (a) with a constant velocity and (b) with anupward acceleration of 1.30 m/s²? (Hint: A free-body diagram can really help.)If the rope on the right extends to the ground and is pulled by a co-worker, with whatforce magnitude must the coworker pull for the man to rise (c) with a constantvelocity and (d) with an upward acceleration of 1.30 m/s2?5.
