Problem 5-62 F, accel., and tension - Part 4 - B

Two blocks are connected by a string passing over a pulley. Neglect friction and the rotation of the pulley. If the masses are m1=3.7kg and m2=2.7kg, determine the magnitudes of:

(a) the acceleration of the blocks

(b) the tension in the string.

[Ans. (a) 5.7m/s2 (b) 15N]
