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! :/
max KE is at the equilibrium point, where PE is zero.
b. Need the graph for that.
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.
