The moment of inertia of a disk is:
A point on the rim of a disk will have a speed of:
Putting all together:
Which for our values is:
Answer:
The negative sign represents the flow of charge in an opposite direction relative to point of action.
The mass of the object does not change by moving it to another place. ... At the center of the earth the net gravitational force is zero, so the weight will be zero, but its masses will remain same. Hence the mass at the centre of earth will be equl to 50 kg.
Negative energy by catching it. Changes the force and movement of the baseball. Loses energy. Kinetic energy
Well you first need an equation, then put it on a graph
