A plane pendulum of length L and mass m is suspended from a
block of mass M. The block moves without friction and is
constrained to move horizontally only (i.e. along the x axis). You
may assume all motion is confined to the xy plane. At t = 0, both
masses are at rest, the block is at
, and the pendulum has angular deflection
with respect to the y axis.

2. (35 points) A pendulum consists of a point mass (m) attached to the end of a spring (massless spring, equilibrium length-Lo and spring constant- k). The other end of the spring is attached to the ceiling. Initially the spring is un-sketched but is making an angle θ° with the vertical, the mass is released from rest, see figure below. Let the instantaneous length of the spring be r. Let the acceleration due to gravity be g celing (a) (10...

A particle is constrained to move in the x - y plane. Its position as a function of time is given by x(t) = x_0 sin(w_xt) and y(t) = y_0 cos(w_yt). Find the force vector F on the particle. Under which condition is the force a central force (i.e., points in the vector r direction)? Find the potential energy for the general force that you found in part (a) (i.e., not necessarily central). Show that the particle's energy is conserved.
