Asingly-charged ion enters a velocity selector that has a 0.18-t magnetic field perpendicular to an electric field of 1.6 kv/m, with both fields perpendicular to the velocity of the ion. the same magnetic field is then used to deflect the ion into a circular path of radius 12.5 cm. what velocity was selected by the velocity selector?

Acaterpillar tries to climb straight up a wall a meter high, but for every 2 cm up it climbs, it slides down 1 cm. eventually, it reaches the top. when it reaches the top, it does not pull itself over so it will slide down 1 cm. what is the total displacement traveled?

Awater slide of length l has a vertical drop of h. abby's mass is m. an average friction force of magnitude f opposes her motion. she starts down the slide at initial speed vi. use work-energy ideas to develop an expression for her speed at the bottom of the slide. then evaluate your result using unit analysis and limiting case analysis. express your answer in terms of the variables h, m, l, vi, f and appropriate constants. vf v f
