Please help me understand this problem One block (m1= 250g) is on a smooth table and connected to amassless string. The string continues over a massless,frictionless, pulley and down towards another block (m2=50.0g) thathangs from the table at the other end of the same string. What isthe magnitude of the acceleration of the block on the table. The answer is 1.63 m/s^2... I can't seem to solve this.

Explanation / Answer
Block 1: T = Fnet : since there is no friction T = m1a Block 2: Fnet = T - Fw m2a = Fw - T T = Fw - m2a Together: m1a = Fw - m2a m1a + m2a = Fw where Fw= m2g a = m2g/(m1+ m2) a = .05kg*9.8/(.25 + .05) = 1.63m/s2 Hope that helps Hope that helps
