Atoy car is given a quick push so that it moves up an inclined ramp. after it is released, it moves up, reaches its highest point and moves back down again. friction is so small it can be ignored. what net force acts on the car? 1. net decreasing force down the ramp 2. net increasing force up the ramp 3. net force of zero 4. net increasing force down the ramp 5. net decreasing force up the ramp 6. net constant force down the ramp 7. net constant force up the ramp

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.
