A 50 kg person jumps off a 210m cliff attached to a 100m bungee cord with a spring constant of 20 N/m. During the first 100m, the person is in free fall. The bungee engages immediately after the 100m mark. a. If the person is 1.6m tall, will they hit the ground? If not, how high above the ground will he reverse direction?

b. If the known tensile strength of the bungee is 2,000 N, will that affect your answer to question 1? Explain.

c. How much was the bungee stretched at the equilibrium position?

If 2 moles of co_2 at 2l and 500k are expanded reversibly to 20l, more work can be obtained from an adiabatic process than from an isothermal process. is the above statement true or false?

The charge on a charged sphere is: a)concentrated at its centerb)distributed uniformly throughout its volumec)clustered on its centerd)distributed uniformly over its surface

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.
