Problem by MILAN J: Locate the power (magnitude and direction) exerted on her by the bungee cord?
A 66-kg bungee jumper has fallen far sufficient that her bungee cord is commencing to stretch and resist her downward motion. Uncover the force (magnitude and course) exerted on her by the bungee cord at an instant when her downward acceleration has a magnitude of six.2 m/s2. Ignore the results of air resistance. Just take the upward course as positive.

downward course beneficial
web power on jumper = ma = mg – F (restoring power, upward)
———————————————–
upward path good
- ma = – mg + F
F = m (g – a) = 66 [nine.8 - 6.two] = + 237.6 N upwards

Problem by donteatthefish: Do you use a bungee office chair?
Do the bungees remain looking very good? The bungees of a Boston Interiors floor model looked frazzled. Do the bungees maintain their tension?
