How far will a hanging 0.400 kg object stretch a spring if its spring
constant is 300 N/m?

M=0.400kg

K=300N/m

E=?

F=?

To find the force

F=mg=0.400x9.8[acceleration due to gravity]

F=3.92N

F=KE

E=F/K

=3.92/300

E= 0.013m

the answer is b ) square root of 5

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
