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