K:kinetic energy(J)

U_s:potential energy of a spring(J)

U_g:gravitational potential energy of a mass(J)

F_s:force exerted by a spring(N)

F_g:force exerted by gravity on a mass(N)

k:spring constant of a spring(N/m)

x:extension or compression of a spring(m)

v:speed of a mass(m/s)

a:acceleration of a mass(m/s²)

m:mass(kg)

g:acceleration due to gravity of a mass(m/s²)

h:vertical displacement of a mass(m)

Newton's 2nd Law:

Total force = mass x acceleration

Hooke's Law:

F_s=-kx

weight(gravitational force on a mass):

F_g=mg

kinetic energy of a mass:

K=½ mv²

potential energy of a spring:

U_s=½ kx²

gravitational potential energy of a mass:

U_g=mgh

For this simulation:

The spring has negligable mass.

No mechanical energy is lost to the environment.

g=−10 m/s²

The positive direction isupwards.

Your answer is 'correct' if it's within
10%of the!0 answer...
unless the!0 answer is zero;
then your answer must also be exactly zero.
