Question

A 65.2 kg bungee jumper is standing on a tall platform (ho 46.2 m), as indicated in the figure. The bungee cord has a natural length of L 8.40 m and, when stretched, behaves like an ideal spring with a spring constant of k 48.3 N/m. The jumper falls from rest, and it is assumed that the only forces acting on him are his weight and, for the latter part of the descent, the elastic force of the bungee cord. What is his speed when he is at the following heights above the water: (a) hA 3 37.8 m, and (b) hB 13.9 m? Lo 8.40 m 46.2 m A 7.8 m B 13.9 m (a) Number Units (b) Number Units

    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...

    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...

    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.
