2016 F = ma Exam — Question 10

Two blocks are suspended by two massless elastic strings to the ceiling as shown in the figure. The masses of the upper and lower block are m = 2 kg and m = 4 kg respectively. If the upper 1 2 string is suddenly cut just above the top block what are the accelerations of the two blocks at the moment when the top block begins to fall? m 1 m 2
