a ball weighing 100 n is shown suspended from a system of cords. what is the tension in the horizontal and angled cords at 50 degrees and 90 degrees

Respuesta :

First, we know that the ball is not in motion, so the acceleration is 0

T45 = Fg/sin45  = 100N/sin 45   = 141 N

Thor = T45 cos 45 = 141 N cos45

= 100 N

hope this helps
