Neco 2022 Physics Question 43 diagram

In the diagram, a block of mass \(m=5\ \text{kg}\) rests on a rough inclined plane that makes an angle of \(30^{\circ}\) with the horizontal. The coefficient of kinetic friction between the block and the plane is \(\mu_{k}=0.20\). The block is attached by a light inextensible string over a frictionless pulley to a hanging mass \(M=3\ \text{kg}\). The system is released from rest and moves with constant acceleration. Determine (i) the magnitude and direction of the acceleration of the system, and (ii) the tension in the string.

Answer Options

Correct Answer A. a = 0.45 \text{m s}^{-2} down the incline; T = 30.7 \text{N}
B. a = 0.55 \\text{m s}^{-2} down the incline; T = 33.2 \\text{N}
C. a = 0.45 \\text{m s}^{-2} up the incline; T = 30.7 \\text{N}
D. a = 0.20 \\text{m s}^{-2} down the incline; T = 25.0 \\text{N}
Correct Answer
A
Correct Option:
a = 0.45 \text{m s}^{-2} down the incline; T = 30.7 \text{N}
