In the phet simulation, estimate the spring constant of spring 1 by hanging masses on it and estimating its elongation. set the friction to maximum to reduce oscillations. which of the following best represents the estimated value of the spring constant?

a) k=5n/m

b) k=7.5n/m

c) k=10,000n/m

d) k=10n/m

The answer is trial 3.

True will be your answer dude

I'm having some difficulty seeing the diagram clearly.but the question says there's a net inward force on the object.so we know right away,  from newton's 2nd law of motion, thatthat baby is accelerating.  it doesn't even matter which way thenet force is pointing.  if there's any net force, then either theobject's speed or else its direction must be changing.
