    Question

    Figure-out the case from the following in which the rope will break if an animal of mass 30 kg climbs on a rope, which can stand a maximum tension of 560 N. Assume g = 10 m/s2\text{m/s}^2

    A.

    8 m/s28\space\text{m/s}^2​​

    B.

    9 m/s29\space\text{m/s}^2​​

    C.

    8.5 m/s28.5\space\text{m/s}^2​​

    D.

    7 m/s27\space\text{m/s}^2​​

    Correct option is B

    Given:Mass of the animal, m=30 kgMaximum tension in the rope, Tmax=560 NAcceleration due to gravity, g=10 m/s2\text{Given:} \\\text{Mass of the animal, } m = 30 \, \text{kg} \\\text{Maximum tension in the rope, } T_{\text{max}} = 560 \, \text{N} \\\text{Acceleration due to gravity, } g = 10 \, \text{m/s}^2

    From the Free Body Diagram (FBD) of the animal:Tmg=maWhere:T=Tension in the rope,m=Mass of the animal,g=Gravitational acceleration,a=Acceleration of the animal.T=m(g+a)Given that the maximum tension is 560 N, we can substitute it into the equation:Tmax=m(g+a)560=30(10+a)560=30(10+a)560=300+30a560300=30a260=30aa=26030=8.67 m/s2\text{From the Free Body Diagram (FBD) of the animal:} \\T - mg = ma \\\text{Where:} \\T = \text{Tension in the rope,} \\m = \text{Mass of the animal,} \\g = \text{Gravitational acceleration,} \\a = \text{Acceleration of the animal.} \\T = m(g + a) \\\text{Given that the maximum tension is 560 N, we can substitute it into the equation:} \\T_{\text{max}} = m(g + a) \\560 = 30(10 + a) \\560 = 30(10 + a) \\560 = 300 + 30a \\560 - 300 = 30a \\260 = 30a \\a = \dfrac{260}{30} = 8.67 \, \text{m/s}^2​​
