The collar of mass m slides on the rough horizontal shaft under the action of the force f of constant magnitude f ≤ mg but variable direction. if ! = kt where k is a constant, and if the collar has a speed v1 to the right when ! = 0, determine the velocity v2 of the collar when ! reaches 90°. also determine the value of f which renders v2 = v1.

(science)study the following ocean currents map. an ocean currents map is shown. on the map the locations for san diego, california and savannah, georgia are marked. there is a looping current from the north past san diego and a looping current from the south near savannah which statement is most likely correct about the average temperatures in san diego, california as compared to savannah, georgia? it is higher in savannah because of the cool ocean currents from the south. it is higher in savannah because of the warm ocean currents from the north. it is lower in san diego because of the warm ocean currents from the south. it is lower in san diego because of the cool ocean currents from the north.
