To test the performance of its tires, a car
travels along a perfectly flat (no banking) cir-
cular track of radius 516 m. the car increases
its speed at uniform rate of
at β‘d |v|Γ·dt = 3.89 m/s^2
until the tires start to skid.
if the tires start to skid when the car reaches
a speed of 32.8 m/s, what is the coefficient of
static friction between the tires and the road? the acceleration of gravity is 9.8 m/s^2

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.
