    Pendulum velocity using energy forumula

    Homework Statement This problem deals with a pendulum. Imagine you're just letting it dangle (so perpendicular to ground) and you lift it to the side by some angle theta. This point your holding it at will be Point A. You release the pendulum from your grip and want to find out at Point B...

    Spring problem using work energy theorem

    Ah so the work done by friction should be negative, right? That still doesn't give me 0.414 though. What else is wrong?

    Spring problem using work energy theorem

    Homework Statement A 2.90 kg block on a horizontal floor is attached to a horizontal spring that is initially compressed 0.0360 m . The spring has force constant 860 N/m . The coefficient of kinetic friction between the floor and the block is 0.35 . The block and spring are released from rest...
