In the system drawn on the right, m_1 = 2.0 kg sits on a lab table which is 110 cm tall. m_2 = 1.0 kg is hanging over a pulley and is initially at rest 60.0 cm above the floor. The system is released. Determine the speed of m_2 just before it hits the floor. (solve with work-energy ideas, considering the system)
a) solve the problem assuming the table is frictionless.
b) coefficient of friction is .2 between m1 and the table
