Two blocks are connected by a string passing over a pulley (Figure
Neglect friction and the rotation of the pulley. If the masses are m1
= 3.7 kg and m2
= 2.7 kg, determine the magnitudes
the acceleration of the blocks
the tension in the string.
(a) 5.7 m/s2 (b) 15 N]
a1 = a2 =a
m2g acts downward and
has no component in the direction of motion.
