    Work-Energy Theorem question with not much detail to work with

    So, I guess initial KE would be 0 as well? The speed is v. So, the final KE would be v-0??

    1/2 mv2 final-1/2 mv2 initial But how do I do that without any numbers?

    Work-Energy Theorem question with not much detail to work with

    Well?? Initial speed is 0, I think, and KE is ?? I don't know, I am so confused. I am trying, but not getting it...

    Work-Energy Theorem question with not much detail to work with

    ΔKE = KE final - KE initial = 1/2 mv2 final - 1/2 mv2 initial Right? So, does this help me? What does that have to do with the hockey stick?

    Work-Energy Theorem question with not much detail to work with

    It states "the net work done by all the forces acting on a body equals the change in its kinetic energy". I don't get it though, how does that help me solve this problem?

    Work-Energy Theorem question with not much detail to work with

    Homework Statement Suppose a hockey puck of mass m is at rest on the ice. A surly Canadian hits the puck and sends it sailing across the ice at velocity v. According to the work-energy theorem, how much work did the player's stick do on the puck?
