1. Between points v0 and v4 describe what is happening to momentum and impulse. 2. Between the points v4 and v8 describe what is happening to momentum and impulse.

3. Calculate the impulse between V0 and V4 for a 50kg object. Show your work and equations.

the chart is in the picture. will mark brainliest if ya'll show how to get the answer.

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.
