Dos esferas de masas m1=0,3gr y m2=0,6gr tienen cargas iguales, están colgadas de un punto en comun. El angulo de separación entre los hilos es de 18° y con una longitud de los hilos de 0,2m calcula: a) cuelgan simétricamente las dos esferas, o son diferentes los ángulos entre la vertical y cada uno de los hilos? Calcule el o los ángulos b) calcule la carga neta de cada esfera

pythagoras' theorem

square root (-5^2+9^2)

square root (25+81)

square root (106)

angle is tan^-1(9/5)

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
