A 160-n child sits on a light swing and is pulled back and held with a horizontal force of 100 n. the magnitude of the tension force of each of the two supporting ropes is:

Respuesta :

The tension on a thing is equivalent to the weight of the object x gravitational force plus/minus the mass x acceleration. But we need to transform its formula, so it will look like:2T = (160^2 +100^2)^.5 
2T = (25600 + 10000) ^ 5
T =94.3398113 N or 94 N
