Three cubes, of side Lo, 2Lo, and 3 Lo, are placed next to one another in contact) with their centers along a
straight line as shown in (Figure 1).
Part A
What is the position, along the line x, of the CM of this system? Assume the cubes are made of the same uniform
material and that CM is measured from the left edge of the smallest cube.
Express your answer in terms of Lo.

Achild throws a ball with an initial speed of 8.00 m/s at an angle of 40.0° above the horizontal. the ball leaves her hand 1.00 m above the ground. how long is the ball in flight before it hits the ground?

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.
