You sign up for a bungee jump off a tall bridge. A thick rope with a fixed length of 16.0 m is tied to the bridge, and a bungee cord with an unstretched length of 8.00 m is then connected to the rope. The other end of the bungee cord is attached to your legs.

You step off the bridge, falling from rest. The bungee cord does not start exerting any force on you until you have fallen a distance of 24.0 m (the sum of the rope's length and the unstretched length of the bungee cord). After that, it exerts an upward force on you that eventually brings you to rest, for an instant. Assume the bungee cord, when stretched, acts like an ideal spring, and take g = 10 N/kg, to make the calculations easier. Your mass is 40.0 kg.

You fall a total distance of 48.0 m before coming instantaneously to rest. Calculate the maximum speed you reach during the fall.

A 90 kg student jumps off a bridge with a 8-m-long bungee cord tied to his feet. The massless bungee cord has a spring constant of 390 N/m. A)How far below the bridge is the student's lowest point? B)How long does it take the student to reach his lowest point? You can assume that the bungee cord exerts no force until it begins to stretch

Chris jumps off a bridge with a bungee cord (a heavy stretchable cord) tied around his ankle, (Figure 1). He falls for 15 m before the bungee cord begins to stretch. Chris's mass is 78 kg and we assume the cord obeys Hooke's law, F=−kx, with 50 N/m . if we neglect air resistance , estimate what distance d below the bridge chris's foot will be before coming to a stop. ignore the mass of the cord and treat chris...

A bungee jumper with mass 59.5 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 43.0 s . He finally comes to rest 21.5 m below the level of the bridge. a)Estimate the spring stiffness constant of the bungee cord assuming SHM. b)Estimate the unstretched length of the bungee cord assuming SHM.

It's your birthday, and to celebrate you're going to make your first bungee jump. You stand on a bridge 110 m above a raging river and attach a 31-m-long bungee cord to your harness. A bungee cord, for practical purposes, is just a long spring, and this cord has a spring constant of 41 N/m . Assume that your mass is 71 kg . After a long hesitation, you dive off the bridge. How far are you above the water...

A daredevil wishes to bungee-jump from a hot-air balloon 73.0 m above a carnival midway. He will use a piece of uniform elastic cord tied to a harness around his body to stop his fall at a point 12.0 m above the ground. Model his body as a particle and the cord as having negligible mass and a tension force described by Hooke's force law. In a preliminary test, hanging at rest from a 5.00-m length of the cord, the...

A venturesome woman plans to bungee jump from a cliff 66.0 m above the ground. She plans to use a uniform elastic cord, tied to a harness around her body, to stop her fall at a point 13.0 m above the water. Model her body as a particle and the cord as having negligible mass and obeying Hooke's law. In a preliminary test she finds that when hanging at rest from a 5.00 m length of the cord, her body...

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 12 m long, and that the cords stretch in the jump an additional 19 m for a jumper whose mass is 120 kg, the heaviest adult you...

If you jump from a desktop and land stiff-legged on a concrete floor, you run a significant risk that you will break a leg. To see how that happens, consider the average force stopping your body when you drop from rest from a height of 1.10 m and stop in a much shorter distance d. Your leg is likely to break at the point where the cross-sectional area of the bone (the tibia) is smallest. This point is just above...
