A bungee jumper who has a mass of 85.0 kg leaps off a very high platform. A crowd excitedly watches as the jumper free-falls, reaches the end of the bungee cord, then gets "yanked" up by the elastic cord, again and again. One observer measures the time between the low points for the jumper to be 9.30 s. Another observer realizes that simple harmonic motion can be used to describe the process because several of the subsequent bounces for the...

An 80.0 kg bungee jumper drops from rest off a bridge that is 200.0 m above a river. As he falls, air resistance is negligible, and the unstretched bungee cord attached to him uncoils. The mass of the bungee cord is negligible. When the jumper is 50.0 m below the bridge, the bungee cord is completely uncoiled and forms a straight line. Below that point, the bungee cord acts as a spring, obeying Hooke's law as it is stretched beyond...

EXAMPLE 6.3 Bungee Jumper A bungee jumper locates a suitable bridge that is 75.0 m above the river below, as shown in Figure 6.14. The jumper has a mass of m-80.0 kg and a height of Ljumper 1.85 m, we can think of a bungee cord as a spring. The spring constant of the bungee cord is k-50.0 N/m. Assume that the mass of the bungee cord is negligible compared with the jumper's mass Lo PROBLENM The jumper wants to...

Consider a bungee jumper dropping vertically in freefall from a bridge 80 m above the ground. After three seconds, the elastic cord connecting the jumper to the bridge starts to stretch, which changes the jumper's acceleration to 15 m/s2 upwards. a) Sketch (without doing any math) the position vs time, velocity vs. time, and acceleration vs. time graphs for the bungee jumper from the moment they start to fall to the moment they reach the closest to the ground. b)...

A bungee jumper of mass 70 kg, ties one end of an elastic rope of length 65 m and stiffness 1.75 kN/m to a bridge and the other end to himself and jumps from the bridge, as shown in the figure below. Assuming the bridge to be rigid, determine the vibratory motion of the jumper about his static equilibrium positiorn. Un-stretched length of 65 m

A 68 kg bungee jumper is standing on a platform 46 m above the ground. The jumper falls from rest and it is assumed that the bungee cord, which is attached to the bungee jumper at one end and the platform at the other, has no effect for the first 9 m of the fall, i.e. the natural length of the cord is 9 m. When the bungee jumper is more than 9 m away from the platform the cord...

Problem 3. A bungee jumper of mass 72.0 kg jumps from a cliff. After reaching his lowest point, he oscil- lates up and down. He is observed to reach his lowest point 9 times more in 45.0 s. Assume the bungee cord obeys Hooke's law. (a) What is the period of his motion? (b) What is the force constant of the bungee cord? (c) After oscillating for a while, the jumper finally comes to rest 30.0 m below his starting...

4./Your adventurous friend Lola goes bungee jumping. She leaps from a bridge that is 100 m above a river. Her bungee cord has an un-stretched length of 50 m and a spring constant k - 600 N/m. Lola has a mass of 48 kg. How fast is she falling when she just starts to stretch the cord? How long does it take for Lola to reach this point? a) Lola stretches the bungee cord and it brings her to a...

When bungee jumping from a high bridge over Victoria Falls, an operator first attaches an elastic rope to the jumper. The jumper then jumps off the bridge, falling freely until they reach the unstretched length of the rope Then, the rope begins to stretch and slows the jumper to a stop. The rope pulls the jumper back up, and they oscillate up and down for a while until the operator pulls the jumper back up to the bridge. The rope...
