72kg is hanging on a rope .what is the force of tension on the rope ?

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:

And therefore

For this problem,

m = 72 kg

Substituting,

you cant move and you feel like someones pushing you down onto your bed it can feel like you want to get up but you just can't it can be extremely scary

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
