Answer:
The equation for speed is : distance divided by time.

From the equation, r is the distance from the center of the tube. When r = 0, you're considered to be at the centerline and the expression has the highest value. Therefore, the velocity of a viscous fluid is greatest at the center of the tube.
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>

Answer:
The force of friction opposes the motion of an object, causing moving objects to lose energy and slow down. When objects move through a fluid, such as air or water, the fluid exerts a frictional force on the moving object. The frictional force from a fluid is called a drag force.
