be locked into two different positions corresponding to
two potential energy levels. Once spring is compressed, the
sphere with the hole slides onto one end of the rod, while
other is placed in a small recess on the opposite side of the
base. On releasing the handle, the potential energy of the
compressed spring imparts horizontal velocity to the solid
sphere while the other sphere simply falls vertically. Falling
of both the spheres on the ground implies that vertical and
horizontal velocities are independent.
