Thanks, I'm not sure how I missed that - I think the first part of this homework fried my brain before I got to this and I just forgot to look at my other equations! However, when I acquired a k value of 49.35 and did the equation in my original post for velocity, I acquired a negative number...

Homework Statement A 200-g object is oscillating in simple harmonic monition with an amplitude of 2 cm and a period of 0.4 seconds. Find the velocity when its displacement from the equilibrium position is 0.5 cm. Homework Equations Restoring Force = -(constant force)(displacement)...

Right, to account for significant figures..got it.

Thus making it 8 N plus 1.96 N, or 9.96 N...thanks a ton!

Ah, I think I understand. If Fnet = Fapplied plus Ffriction, and Ffriction opposed the Fnet making it negative, then that would make the equation Fnet = Fapplied minus Ffriction, so the Fapplied would be Fnet plus Ffriction...is that correct?

So, would I be correct in subtracting the friction force of 1.96 N from the net force of 8 N, since they oppose each other?

Homework Statement A certain force moves a 4-kg box from rest to a velocity of 6 m/s in 3 seconds. If the coefficient of friction between the box and the floor is 0.05, what is the magnitude of the force? Given/Known: mass = 4 kg μ (I'm assuming it means kinetic friction?) = 0.05 time = 3...
