9) A rock is projected upwards from the surface of the moon at time t = 0.0 s with a velocity of 30 m/s (the acceleration due to gravity at the surface of the moon is -1.62 m/s2. The rock rises, then falls and strikes the ground. Consider all quantities as positive in the upward direction. What is the velocity during accent at 180 m above the surface? At time t = 10 s, what is the height of the rock from the ground?
Answers: 3
(1) 
- Initial velocity, measured in meters per second.
- Final velocity, measured in meters per second. 
- Gravitational acceleration, measured in meters per square second. 
- Travelled distance, measured in meters.
, 
and 
, then the velocity during ascent at 180 meters is:
(2) 
- Initial position of the rock, measured in meters.
- Final position of the rock, measured in meters.
- Time, measured in seconds.
,

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.
