Whenever you work a physics problem you should get into the habit of thinking about whether the answer is physicallyrealistic. Think about how far off the ground a typical small truck is. Is the answer to Part B physically realistic?Select the best choice below. a. No, typical small pickup truck springs are not large enough to compress 0.61{\rm m}.b. Yes, typical small pickup truck springs can easily compress 0.61{\rm m}

Alarge cruise ship of mass 7.00 ✕ 107 kg has a speed of 11.6 m/s at some instant. (a) what is the ship's kinetic energy at this time? (b) how much work is required to stop it? (give the work done on the ship. include the sign of the value in your answer.) (c) what is the magnitude of the constant force required to stop it as it undergoes a displacement of 3.00 km?

The nuclear potential that binds protons and neutrons in the nucleus of an atom is often approximated by a square well. imagine a proton conned in an innite square well of length 105 nm, a typical nuclear diameter. calculate the wavelength and energy associated with the photon that is emitted when the proton undergoes a transition from the rst excited state (n 2) to the ground state (n 1). in what region of the electromagnetic spectrum does this wavelength belong?
