Two masses, \(m_1 = 3.0\ \text{kg}\) and \(m_2 = 5.0\ \text{kg}\), are connected by a light inextensible string passing over a frictionless pulley. (a) When the system is released from rest, determine (i) the magnitude of the acceleration of the masses and (ii) the tension in the string. (b) If, during the motion, a constant upward force of \(10\ \text{N}\) is applied to the heavier mass \(m_2\), find the new acceleration of the system.

Answer Options

A. a = 3.10 m\/s^2, T = 40.5 N; a' = 1.50 m\/s^2
B. a = 2.00 m\/s^2, T = 30.0 N; a' = 0.80 m\/s^2
C. a = 1.75 m\/s^2, T = 28.0 N; a' = 0.60 m\/s^2
Correct Answer D. a = 2.45 m/s^2, T = 36.8 N; a' = 1.20 m/s^2
Correct Answer
D
Correct Option:
a = 2.45 m/s^2, T = 36.8 N; a' = 1.20 m/s^2
