Question

All surfaces shown in figure are assumed to be frictionless and the pulleys and the string are light. The acceleration of the block of mass 2 kg is:

TestHub · Accepted Answer

For 4 kg block: 40 - 2 T = 4 a ⇒ T = 20 - 2 a For 2 kg block: T - 10 = 4 a ⇒ 20 - 2 a - 10 = 4 a ⇒ 10 = 6 a ⇒ a = 10 6 = g 6 m s - 2 Acceleration of the block of mass 2 kg , 2 a = g 3 m s - 2 .
