Question
1. An undamped harmonic oscillator of mass m and spring constant k oscillates with an amplitude A. In
terms of A, at what postion x is the speed of the oscillator, v, is half of its maximum speed vmax-
Think & Prepare
1. Set-up the mechanical energy equation at any postion in terms of the variables of m, k and A. In
particular, set-up up two equations, one equation at x when v= vmax!
x/2 and one at x= A.
2. Is the mechanical energy conserved? If so, what how are the two energy equations in 1 related?
3. Solve for x when v= vmax/2 in term of the amplitude A.
4. How many solutions for x are there?
x when v is
Vmax = ±E
