Physics Help!!!!! Maximum Kinetic Energy based on a graph?
A 2.50kg ball is attached to an unknown spring and allowed to oscillate. The figure shows a graph of the ball’s position x as a function of time t.(Figure 1)


Part A: What is the maximum kinetic energy of the vibrating ball?
Part B: When does it occur?
I am so lost. I feel like there's not even enough info to begin! :/

  • Physics -

    max KE is at the equilibrium point, where PE is zero.

    b. Need the graph for that.

  • Physics -

    Maximum kinetic 3nergy is achieved when the spring is in the unstretched poition.

    Without knowledge of the spring constant and amplitude, or the maximum velocity, I cannot tell you what the maximum kinetic energy is.

    Your figure probably has that information.
