A 125 g weight is hung from a spring with a spring constant of 25 N/m. The position of the mass is measured from the equilibrium point. The mass is pulled down 15 centimeter and released at t=0. The position of the mass is given by x (t) = xo cos (wt = theta o)
Find what are the values of all the constants in this equation?
Calculate the maximum energy of the mass?
Find at what time will the position be 5.0 centimeter? Memorize to do dimensions check and limiting cases.
