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
A.
8m/s2
B.
9m/s2
C.
8.5m/s2
D.
7m/s2
Correct option is B
Given:Mass of the animal, m=30kgMaximum tension in the rope, Tmax=560NAcceleration due to gravity, g=10m/s2
From the Free Body Diagram (FBD) of the animal:T−mg=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+30a560−300=30a260=30aa=30260=8.67m/s2
