1. The problem statement, all variables and given/known data Two particles A and B, of masses 2m kg and m kg respectively, are connected by a light inextensible string which passes over a fixed smooth pulley. The system is RELEASED from REST, with both portions of the string vertical and taut, while A and B are at the SAME HEIGHT. 1. Find the magnitude of the acceleration of the particles and the tension in the string. The string breaks when the speed of each particle is u m/s. Find, in terms of u, the difference in height between the particles A and B: 2. When the string breaks 3. When B reaches its highest point, assuming that A has not reached the ground and B has not reached the pulley. Find the speed of A when B reaches its highest point. 2. Relevant equations F = ma g = 10 m/s^2 3. The attempt at a solution (2m)(a) = (2m)(10 m/s^2) - T -- (1) (m)(a) = T - (m)(10) -- (2) (2m)(10) - (2m)(a) = (m)(a) + (m)(10)... Rearranging this in order to solve for a and I got a = 3.33 m/^2 -- (3) Plugging (3) in (1) or (2) in order to solve for T and I got 13.33 Now can anyone help me with the rest? I'm lost with #2 and #3.
