Answer :
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
