Juan inflates a balloon and then releases its end to let the balloon go free as air comes out. the balloon then flies around the room. which statement describes how this example is an application of newton’s laws of motion? according to newton’s first law of motion, the balloon continues moving until the forces on it are balanced. according to newton’s third law of motion, the balloon is pushed forward as the air is forced out. according to newton’s third law of motion, the balloon resists any change of motion unless an unbalanced force acts upon it. according to newton’s second law of motion, the balloon exerts a force on the air, which exerts a force back on the balloon.

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.
