A 100 gram weight is hung from a spring with a spring constant of 10 N/m. the position of the mass is measured from he equilibrium point. The mass is pulled down 10 cm and released at T=0.
The position of the mass is given by x(t)=xcos(wt+theta).
What are the values of all the constants in this equation?
What is the maximum kinetic energy of the mass?
At what will the position be at 5 cm?
