A 61 kg bungee jumper jumps from a bridge. At the point when she is travelling 22 m/s, the cord starts to stretch. The cord stretches 28 m before causing her to stop completely for a moment. How fast is she travelling when the cord is stretched 12 m? Please show all of your work.

A 61 kg bungee jumper jumps from a bridge. At the point when she
is travelling 20 m/s, the cord starts to stretch. The cord
stretches 25 m before causing her to stop completely for a moment.
How fast is she travelling when the cord is stretched 12 m?

A bungee jumper with mass 64.5 kg jumps from a high bridge.
After arriving at his lowest point, he oscillates up and down,
reaching a low point seven more times in 44.0 s . He finally comes
to rest 20.5 m below the level of the bridge.
Part A
Estimate the spring stiffness constant of the bungee cord
assuming SHM.
Part B
Estimate the unstretched length of the bungee cord assuming
SHM.

A bungee jumper with mass 58.5 kg jumps from a high bridge.
After arriving at his lowest point, he oscillates up and down,
reaching a low point seven more times in 41.0 s . He finally comes
to rest 20.0 m below the level of the bridge. Part A Estimate the
spring stiffness constant of the bungee cord assuming SHM. Part B
Estimate the unstretched length of the bungee cord assuming
SHM.

A bungee jumper of mass 110 kg jumps from a cliff of height
120m. The massless relaxed bungee cord has a length of 15 m. Ignore
the height of the body of the jumper. K=125N/m. (a) Find the
velocity of the jumper right before the bungee starts to stretch.
(b) Find the distance the cord stretches.
Please explain the steps. Thank you!

A 74.0-kg bungee jumper steps off a bridge with a light bungee
cord tied to her and to the bridge. The unstretched length of the
cord is 14.0 m. The jumper reaches reaches the bottom of her motion
40.0 m below the bridge before bouncing back. We wish to find the
time interval between her leaving the bridge and her arriving at
the bottom of her motion. Her overall motion can be separated into
an 14.0-m free-fall and a 26.0-m...

A bungee jumper plans to bungee jump from a bridge 74.0 m above
the ground. He plans to use a uniform elastic cord, tied to a
harness around his body, to stop his fall at a point 6.00 m above
the water. Model his body as a particle and the cord as having
negligible mass and obeying Hooke's law. In a preliminary test he
finds that when hanging at rest from a 5.00 m length of the cord,
his body...

A 90 kg student jumps off a bridge with a 10-m-long bungee cord
tied to his feet. The massless bungee cord has a spring constant of
390 N/m. You can assume that the bungee cord exerts no force until
it begins to stretch.
How far below the bridge is the student's lowest point?
How far below the bridge is the student's resting position after
the oscillations have been fully damped?

A 75 kg student jumps off a bridge with a 12-m-long bungee cord
tied to his feet. The massless bungee cord has a spring constant of
430 N/m. a. How far below the bridge is the student’s lowest point?
b. How far below the bridge is the student's resting position after
the oscillations have been fully damped?

A bungee jumper (mass 80 kg) is attached to a 10 m bungee cord
attached to the top of a crane. For the first 5 meters of
extension, the force exerted by the bungee cord increases by 2 N
for every 1 cm. For any further extension, the force increases by
only 1.2 N for every 1 cm..
a) Sketch the elastic force vs the length of the bungee
cord.
b) What is the maximum extension of the bungee cord...

Design a "bungee jump" apparatus for adults
. A bungee jumper falls from a high platform with two elastic
cords tied to the ankles. The jumper falls freely for a while, with
the cords slack. Then the jumper falls an additional distance with
the cords increasingly tense. Assume that you have cords that are
11 m long, and that the cords stretch in the jump an additional 23
m for a jumper whose mass is 140 kg, the heaviest adult...
