We can use the formula of the moment of inertia given by:

Where:
r = Distance from the point about which the torque is being measured to the point where the force is applied
F = Force
I = Moment of inertia
α = Angular acceleration
So:

Answer:
12 rad/s²
 
        
             
        
        
        
What happened to the scientists' estimates of the Earth's age in the year 1650 since then the scientists now think the earth is much older. Currently Earth's age is approximately <span>4.543 billion years.

The amount of gravitational potential energy acquired by the rock is equal to:

where 
m is the mass of the rock
g is the gravitational acceleration

 is the increase in height of the rock
Substituting the data of the problem, we find

So, Natalie gave 220.7 J of energy to the rock.
