4.2.6. [Level 1] Consider a cyclist who comes to a stop at a stop sign and then begins to topple over. Because his feet are clipped into the pedals, he falls helplessly to the side. At this point many people would put out their hand to break the fall, leading to a wrist injury. Being a smarter cyclist, our rider keeps his hands on the handlebars and therefore top- ples all the way over and finally strikes the ground with his upper torso. We will consider the simplest approximation to this problem and model the cyclist as a lumped massm atop a massless rod of length h. The mass will contact the ground with a speed v after the rod has pivoted by Find v for a height of 1 m. rad.
