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]

 

ACCUMULATED SOLUTION

a₁ = a₂ =a

 

No. m₂g acts downward and has no component in the direction of motion.
