A bungee cord is 30.0 m long and, when stretched a distance x, it exerts a restoring force of magnitude kx. Your father-in-law (mass 94.0kg ) stands on a platform 45.0 m above the ground, and one end of the cord is tied securely to his ankle and the other end to the platform. You have promised him that when he steps off the platform he will fall a maximum distance of only 41.0 mbefore the cord stops him. You had several bungee cords to select from, and you tested them by stretching them out, tying one end to a tree, and pulling on the other end with a force of 410N .
When you do this, what distance will the bungee cord that you should select have stretched?

A bungee cord is 30.0 m long and, when stretched a distance x,
it exerts a restoring force of magnitude kx. Your father-in-law
(mass 93.0 kg ) stands on a platform 45.0 m above the ground, and
one end of the cord is tied securely to his ankle and the other end
to the platform. You have promised him that when he steps off the

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...

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 0.49-kg cord is stretched between two supports,7.3m apart. When one support is struck by a hammer, a transverse wave travels down the cord and reaches the other support in 0.83s .
What is the tension in the cord? (Express your answer to two significant figures and include the appropriate units.
