Ek = 1/2 x m x v ²
1/2 x 620.0 x 9.00 ² = 25,100
Yes, our friend is right, because there is no contradiction to the law of conservation of mass in the above equation. It just the mass of the product is equal to the mass of reactants.. and that is shown in the equation you have presented earlier
Answer:
The value of spring constant is 266.01
Explanation:
Given:
Mass of pellet kg
Height difference of pellet rise m
Spring compression m
From energy conservation law,
Spring potential energy is stored into potential energy,
Where spring constant,
Therefore, the value of spring constant is 266.01
