    Help finding the change in potential energy in this problem

    sorry, i meant tension is the centripetal force of the puck so: T = mac

    Help finding the change in potential energy in this problem

    Thank you for replying again, and I think that the Tension corresponds to the rotational speed of the puck

    Help finding the change in potential energy in this problem

    Hi, thank you for replying. I believe the forces on the block are the tension force from the string and gravitational force; hence, these two forces would be opposing each other as the block hangs at rest. Since it hangs at rest the net force would be equal to zero. Equation i would write...

    Help finding the change in potential energy in this problem

    Hi guys, I was able to get the answer for part A. but I am having trouble finding the answer for part B. From my understanding, in order to get the answer for part B: first, we need to determine the force that the puck exerts with its new speed which is 1/4 of the original speed obtained from...
