4. a 62.0-kg person, standing on the diving board, dives straight down into the water. just before striking the water, her speed is 5.50 m/s. at a time of 1.65 s after she enters the water, her speed is reduced to 1.10 m/s. what is the net average force (magnitude and direction) that acts on her when she is in the water?

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?
