Problem 5-62 F, accel., and tension

Two blocks are connected by a string passing over a pulley. 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) $15\; N$]

The accelerations of the blocks 1 and 2 are:

(A)   $\text{equal}$

(B)   $a_1 > a_2$

(C)   $a_1 < a_2$
