Mass on Cart Using an Ideal Hard Stop

This example shows a cart bouncing between the two ends of an ideal hard stop, while a mass slides freely on top of it. The friction between the mass and cart is modeled using an ideal, modechart-based friction block, while the hard stop is modeled using instantaneous modes and entry actions. When the cart hits the bounds of the hard stop, the impulsive force is propagated to the mass above, causing it to be displaced as it transitions from static to dynamic friction modes.
