( Atwood's Machine) A mass of 250 grams and a radius of 25 cm. Mass m1 is 180 grams and m2 is 300 grams. The rope does not slip on the pulley. Hint: The two sides of the rope do not have the same tension with a massive pulley.
a) Draw free-body diagrams for m1, m2, and the pulley (Atwood's machine).
b) Find the F=ma equations for each mass and the for the pulley
