PhysicsSingle correct+4 / -1Question 48 of 90

A monkey of mass 50 kg climbs on a rope which can withstand the tension (T) of 350 N. If monkey initially climbs down with an acceleration of 4 m/s $^2$ and then climbs up with an acceleration of 5 m/s $^2$ . Choose the correct option ( $g=10$ m/s $^2$ ).

T = 700 N while climbing upward

T = 350 N while going downward

Rope will break while climbing upward

Rope will break while going downward

Answer and worked solution

Official answer: C

Down: $T=50(10-4)=300$ N. Up: $T=50(10+5)=750$ N > 350 N: the rope breaks while climbing up.

(C)

Topics:Newton's laws
