Question

A 50 kg monkey climbs a rope that can withstand 350 N. It first climbs downward with acceleration 4 m s⁻² and then upward with acceleration 5 m s⁻². Take g=10 m s⁻². Which is correct?

G1 Physics · Accepted Answer

Downward acceleration: T=m(g-a)=50×6=300 N, safe. Upward acceleration: T=m(g+a)=50×15=750 N>350 N. Thus the rope breaks while climbing upward.
