A cylinder of mass M = 2 kg and moment of inertia MR2/2 has a light thread wrapped several times around it. The free end of the thread is
attached to a mass m = 4 kg. Determine the acceleration of the mass
and the tension in the string when the mass is released from rest. Need work to prove my answer.

Scientist have use computer models to create a series of maps that show how susceptible coastal cities in island countries are to the sea rising at different levels. the map shows that a 1 meter rise would swap cities all along the us eastern seaboard. a 6-meter sea level rise with sub merge a large part of florida. thermal expansion has already raise the oceans 10 to 20 centimeters the most likely cause, directly and indirectly, for such a rise in sea level is
