Most Likely Answer:
It cannot be determined without knowing the mass of the sphere.
<span>Even in space, there is still presence of gravity. The
cause of weightlessness is not how far above the earth the space shuttle is but
rather how fast it is travelling. The shuttle is in free fall causing
weightlessness, but it is travelling fast enough to miss the earth as it falls.
Similarly, the airplane could also provide weightlessness if it went free fall
as well. However, that ends as the plane hits the ground. </span>
Answer:
the tension T = 916[N]
Explanation:
We need to analyze the sketch that is in the attached image, here we can find the free body diagram with the forces acting over him.
The weight is equal to the product of the mass by the gravity
w = m*g = 78.9[kg] * 9.81[m/s^2]
The acceleration given by the helicopter is 1.8 [m/s^2]
The sum of forces on the body must be equal to mass by acceleration.
The only forces acting are the tension of the cable and the weight of man, these forces are equal to the product of mass by acceleration.
The substance is deoxyribonucleic acid (DNA)!
