1. The problem statement, all variables and given/known data A wooden toy mouse of mass (m) is attached to a spring with constant (k) and suspended vertically as shown below. The toy is released at the point the spring is unstretched at position x = +A, passes through equilibrium at x = 0 and the spring’s maximum extension occurs at x = -A. If we ignore air friction and assume an ideal spring calculate expressions for the kinetic energy Ek, the elastic potential energy E elast, the gravitional potential energy E pot,and the total energy of the system Etotal, at (i) the release point and (ii) the equilibrium point. Take the gravitational potential energy to be zero at the equilibrium point y=0 and note that for a mass on a spring the maximum velocity vm=wA where w= sqrt (k/m) 2. Relevant equations pe=1/2kx^2 e=mgh X= acoswt K=mw^2 3. The attempt at a solution For equilibrium, I wrote for kinetic expression, since equation is 1/2 kx^2 i substitued the equation k mw^2, and since x was 0 and i cancelled the term and derived the equation 1/2 mw^2. Could you please tell me if im right?
