The driver of a Porsche 944 is traveling down a one lane country road at 27 m/s. He travels around a curve in the road and a large moose standing in the
road 40 m ahead of him. If the maximum deceleration which can be supplied
by his brakes and tires is 8.5 m/s/s, determine whether or not he can he avoid
a crash. Solve using equations.

Consider a double atwood machine constructed as follows: a mass 4m is suspended from a string that passes over a massless pulley on frictionless bearings. the other end of this string supports a second similar pulley, over which passes a second string supporting a mass of 3m at one end and m at the other. using two suitable generalized coordinates, set up the lagrangian and use the lagrange equations to find the acceleration of the mass 4m when the system is released. explain why the top pulley rotates even though it carries equal weights on each side.
