1)A mass 'm' is dropped from a spring with constant 'k'. find the time it takes to reach equilibrium.
im pretty sure i can use this eqn
T = 2*PI*sqrt(m/k)
2)find the tension at the lowest point of the pendulum, with length L and mass M.
there will be zero work done by tension at the bot, it is at a r. angle. I am thinking you have to use k + U = k_0 + U_0 for conservation of mechanical energy, but i was also thinking of using the y component of the problem.
T - m*g = a * m
a = v^2 / r
T = m*g + m*(v^2/r)
v = omega*r and omega = sqrt (g/L)
T = m*g +(m*g) / L
this doesn't seem right
