A gymnast of mass 60kg hangs from a vertical rope attached to the ceiling. You can ignore the weight of the rope and assume that the rope does not stretch. Use the value 9.81 for the acceleration of gravity.
How long after the beginning of the power failure would it have taken the flywheel to stop if the power had not come back on? Explain how many revolutions would the wheel have made during this time?
A concrete highway curve of radius 60 m is banked at a 13.0^circ angle. What is the maximum speed with which a 1300 kg rubber-tired car can take this curve without sliding? (Take the static coefficient of friction of rubber on concrete to be 1.0.)
An astronaut travels to an alternate universe that contains infinite charged plane and no other charged objects. The astronaut observes that the electric field in this universe has a magnitude of 1.20 N/C everywhere and points directly away from the ..
