Assuming that they are
pulling the space shuttle straight up, and that this is done on the surface of
the earth, where gravity is equal to 9.8 m/s^2. So taking the average pull force
of a person to be 110 kg, then: <span>
110 kg/person * 9.8 m/s^2 = 1078 kg*m/s^2, or 1078 N/person
(Newtons). </span>
1 Newton is about 0.225
lb. So, 1078 N/person * 0.225 lb/N = 242.34 lb/person. <span>
So if the space shuttle weighs 4,500,000 lb, then it would
take 4,500,000 lb / (242.34 lb/person) = 18,569 people. </span>
Answer:
<span>18,569 people</span>
