A 2 kg mass, tied with a weightless string that passes over a smooth pulley, is being pulled due to the vertical fall of a 3 kg mass tied to the other end of the string. The string snapped 5 s after the fall started . What further distance does the 2 kg mass rise through?
(g = 10 m`cdot s^(-2)`)

A smooth massless string passes over a smooth fixed pulley. Two masses m_1 and m_2 (m_1 > m_2) are tied at the two ends of the string. The masses are allowed to move under gravity starting from rest. The total external force acting on the two masses is

A pair of parallel horizontal conducting rails of negligible resistance shorted at one end is fixed on a table. The distance between the rails is L.A conducting massless rod of resistance R can slide on the rails frictionlessly. The rod is tied to a massless string which passes over a pulley fixed to the edge of the table. A mass m, tied to the other end of the string, hangs vertically. A constant magnetic field B exists perpendicular to the table. If the system is released from rest. Calculate (a) the terminal velocity achieed by the rod and (b) the acceleration of the mass at the instant, when the velocity of the rod is half the terminal velocity.
