5-62. Two blocks are connected by a string passing over a pulley (Figure 4-22). Neglect friction and the rotation of the pulley. If the masses are
m
1
= 3.7 kg and
m
2
= 2.7 kg, determine the magnitudes of:
(a) the acceleration of the blocks
(b) the tension in the string.
[Ans. (a) 5.7 m/s
2
(b) 15 N]
ACCUMULATED SOLUTION
