In 1865 jules verne proposed sending men to the moon by firing a space capsule from a 220-m-long cannon with final speed of 10.97 km/s. what would have been the unrealisti- cally large acceleration experienced by the space travelers during their launch? (a human can stand an acceleration of 15g for a short time.) compare your answer with the free-fall acceleration, 9.80 m/s^2? .

An electron and a proton have the same kinetic energy upon entering a region of constant magnetic field and their velocity vectors are perpendicular to the magnetic field. suppose the magnetic field is strong enough to allow the particles to circle in the field. note: you'll need to look up the masses for an electron and proton. 1) what is the ratio of the radii of their circular paths rp/re?
