Answer:
705.6 N
Explanation:
The object is hanging on the rope, so there are two forces acting on the object:
- The force of gravity, downward, equal to
W = mg
where m is the mass of the object and g the acceleration of gravity
- The tension in the rope, T, upward
Since the object is hanging motionless, the object is in equilibrium, so we can write:
[tex]T-mg=0[/tex]
And therefore
[tex]T=mg[/tex]
For this problem,
m = 72 kg
[tex]g=9.8 m/s^2[/tex]
Substituting,
[tex]T=(72)(9.8)=705.6 N[/tex]
