Fusion is the energy source of stars. The energy that is being released from the gas collapse into a protostar causes the center of the protostar to become extremely hot. Once the core is hot enough, nuclear fusion commences. The fusion reaction is a very structured process, releasing a huge amount of energy.

Objects of equal mass are oscillating up and down in simple harmonic motion on two different vertical springs. The spring consta
Zanzabum

Answer:

k_2=920\ N/m

Explanation:

Given that,

The spring constant of spring 1, k_1=230\ N/m

The motion of the object on spring 1 has twice the amplitude as the motion of the object on spring 2, A_1=2A_2

As the magnitude of the maximum velocity is the same in each case, it means the maximum kinetic energy is same in each case. In other words, the total energy is same.

\dfrac{1}{2}k_1A_1^2=\dfrac{1}{2}k_2A_2^2

k_1A_1^2=k_2A_2^2

k_1(2A_2)^2=k_2A_2^2

k_2=920\ N/m

So, the spring constant of spring 2 is 920 N/m. Hence, this is the required solution.
