Part A) A pulley is massless and frictionless. The masses 3 kg, 3 kg, and 7 kg are suspended as in the figure. What is the tension T1 in the string between the two blocks on the left-hand side of the pulley?
The acceleration of gravity is 9.8 m/s^2.
Answer in units of N.
Part B) What is the magnitude of the acceleration of the lower left-hand block?

Answer:

Explanation:

find the system acceleration

F = ma

7g - 3g -3g = (7 + 3 + 3)a

1(9.8) = 13a

a = 9.8/13 m/s²

String tension must support weight and provide for acceleration.

F = ma

T₁ = 3(9.8 + 9.8/13)

T₁ = 31.7 N
