Answer:
H = 5.35 cm
Step-by-step explanation:
As per energy conservation we know that energy stored in the spring is converted into gravitational potential energy when it is reached at the top
now we have
![(1)/(2)kx^2 = mgh](https://img.qammunity.org/2020/formulas/physics/college/oajra5mr4iz8rsdz72jwjzo0yaarxzog4a.png)
here we know that
m = 1 kg
k = 105 N/m
x = 0.1 m
now plug in all data in it
![(1)/(2)(105)(0.1^2) = 1(9.81)(H)](https://img.qammunity.org/2020/formulas/physics/college/6kk71rrh9d4fy2m84q4njxsgoxlk1799w2.png)
now solving for height H we have
![H = 0.0535 m](https://img.qammunity.org/2020/formulas/physics/college/7jaysgqlqia050l87723sojxlh8hkgsg2i.png)
