A spring is pulled to 10 cm and held in place with a force of 500 N. What is the spring constant of the spring in N/cm?

K=50N/cm

Explanation:

Force can be calculated using below expresion;

F=ke

where f = force,

k =spring constant,

e = extension

force = 500 N

e= 10 cm =

Then substitute, the given values

500=10 × k

k=500/10

K=50N/cm

object 2 because all the other ones are wrong

another example of kinetic energy would be,

kinetic energy   >     moving energy
