Aproton traveling with velocity 3.60 x 10^4 m/s enters a region of space where there is an electric field e = -5.0 x 10^5 n/c. (a) what is the proton's acceleration?
(b) after it enters the electric field, how much time passes before the proton comes to rest?
(c) how far does it travel in the field before coming to rest?

If the speed of a particle triples ,by what factor does its kinetic energy increase?

Tafari worked one summer on a ship that set weather buoys in the ocean. he watched how one of the buoys moved in the water. describe which parts of the wave would cause the buoy to bob up and down. which wave property determined how fast the buoys bobbed in the water? he observed that when the wind blew harder, the ocean waves were larger, and the buoys moved away from the ship. what effect, if any, did the waves have on how far the buoys moved? explain your answer.

The uniform slender bar rests on a smooth horizon- tal surface when a force f is applied normal to the bar at point a. point a is observed to have an initial acceleration aa of 20 m/s2, and the bar has a corre- sponding angular acceleration of 18 rad /s2. deter- mine the distance b.
