Question

A spring attached to a mass is at rest in the initial position (not shown). The spring is compressed in position A and is then released, as shown in position B. Which equation describes the conservation of energy in position A?


`E=(1)/(2) mv^(2) \\E=mgh\\E=(1)/(2) kx^(2) \\E=(1)/(2) k2kx^(2)`

Answer 1

Step-by-step explanation:

The energy conservation is equal to half of the product of the spring constant and the square of displacement of the spring, so option C is correct.
