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 m1
= 3.7 kg and m2 = 2.7 kg, determine the magnitudes
of:(a)
the acceleration of the blocks
(b)
the tension in the string.
[Ans.
(a) 5.7 m/s2 (b) 15 N]
Correct!
The accelerations are equal: a1
= a2 = a
The force that accelerates m2 is:
(A) T (the tension in the string)
(B) m2g (the weight of m2)
