A \(3.0\ \text{kg}\) block rests on a \(25^{\circ}\) incline. The coefficient of kinetic friction between the block and the plane is \(0.15\). The block is attached by a light inextensible string over a frictionless pulley at the top of the incline to a hanging mass of \(2.0\ \text{kg}\). The system is released from rest. (a) Find the acceleration of the system. (b) Determine the tension in the string.

Answer Options

Correct Answer A. a = 0.64 m/s²; T = 18.3 N
B. a = 0.64 m\/s²; T = 22.0 N
C. a = 0.80 m\/s²; T = 20.5 N
D. a = 0.45 m\/s²; T = 15.2 N
Correct Answer
A
Correct Option:
a = 0.64 m/s²; T = 18.3 N
