Answer:
The right solution will be the "2v".
Explanation:
For something like an object underneath pure rolling the speed at any point is calculated by:
⇒ 
Although the angular velocity was indeed closely linked to either the transnational velocity throughout particular instance of pure rolling as:
⇒ 
Significant meaning is obtained, as speeds are in the same direction. Therefore the speed of rotation becomes supplied by:
⇒ 
On substituting the estimated values, we get
⇒ 
⇒ 
So that the velocity will be:
⇒ 
⇒ 
Explanation:
According to the law of conservation of mass, the masses at the start and finish of a reaction will stay the same. The law of conservation of mass "mass is always constant in a chemical reaction".
- The law is the basis for chemical calculations.
- Masses of reactants and products must be the same to show that mass is always conserved.
- Disparity in the mass could result from loss of mass to the environment or some side reactions that cannot be easily monitored.

OK think of it distance,The smaller the distance less momentum is needed the Longer the distance the the longer the momentum is needed.
