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 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]
The accelerations of the blocks 1 and 2 are:
(A) equal
(B)a1
> a2
(C) a1
< a2
