Explanation:
The angular momentum is given by the moment of inertia, multiplied by the angular speed of the rotating body:
The angular speed is given by:
Now, we calculate the angular momentum:
The average torque is defined as:
is the angular acceleration, which is defined as:
We have to calculate :
Now, we calculate the angular acceleration:
Finally, we can know the average torque:
One very useful definition if energy is "the ability to do work".

Answer:
The wedge balances propelled force.
Explanation:
According to the laws of motion, when appropriate weight is employed properly, a ball can move a truck. The same basic functions apply in this scenario. You often find a woodcutter raising the axe and letting it fall into the wood. This allows force to equally generate at both sides of the axe, splitting the wood apart.
