Chapter 9, Problem 35EAP
Assessing Impact Danger. Roles: Scribe {collects data and takes notes on the group's activities), Proposer (proposes hypotheses and explanations of the data), Skeptic (points out weaknesses in the hypotheses and explanations}, Moder:ator (leads group discussion and makes sure everyone contributes). Activity: Assess the risks we face on Earth from meteorite and comet impacts as follows.
- Consider the question of the odds that human civilization will be destroyed by an impact during your lifetime. Determine the kinds of information you would need, develop a method for making the estimate, and write down your method.
- Analyze Figure 9.27 1£1and determine whether it contains any of the necessary information.
- App ly your group's method to estimate the probability that civiliza,tion will be destroyed by an impact during your lifetime, which you can assume to be 100 years for the purpose of this exercise.
- Estimate the probability that an impact will cause "widespreaddevastation" somewhere on Earth during your lifetime.
- Finding near-Earth asteroids earily greatly increases our chances of deflecting them. Given the probabliities from parts c and d and cons idering the damage these events would cause, decide as a group how much money per year should be spent on finding near-Earth asteroids and explain your reasoning.

- A bungee jumper plans to bungee jump from a bridge 64.0 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 weight stretches it by 1.55 m. He will drop from rest at the point where the top end of a longer section of the cord is attached to the bridge. (a) What length of cord should he use? Use subscripts 1 and 2 respectively to represent the 5.00 m test length and the actual jump length. Use Hooke's law F = KAL and the fact that the change in length AL for a given force is proportional the length L (AL = CL), to determine the force constant for the test case and for the jump case.

(Enter your answer in m.)arrow_forwardTruck suspensions often have "helper springs" that engage at high loads. One such arrangement is a leaf spring with a helper coil spring mounted on the axle, as shown in the figure below. When the main leaf spring is compressed by distance yo, the helper spring engages and then helps to support any additional load. Suppose the leaf spring constant is 5.05 × 105 N/m, the helper spring constant is 3.50 × 105 N/m, and y = 0.500 m.
