Answer:

584 N

Explanation:

Draw a free body diagram of the seat. There are 2 forces:

Weight force mg pulling down,

Tension force T pulling up 38.2° from the vertical.

Sum of forces in the y direction:

∑F = ma

T cos θ − mg = 0

T = mg / cos θ

T = (36.8 kg + 10 kg) (9.8 m/s²) / cos 38.2°

T = 584 N
