Aircraft sometimes acquire small static charges. suppose a supersonic jet has a 0.650 µc charge and flies due west at a speed of 540 m/s over the earth's south magnetic pole, where the 8.00 ✕ 10−5 t magnetic field points straight up. what are the magnitude (in n) and direction of the magnetic force on the plane?

You are driving to the grocery store at 20 m/s. you are 110m from an intersection when the traffic light turns red. assume that your reaction time is 0.50s and that your car brakes with constant acceleration. how far are you from the intersection when you begin to apply the brakes? what acceleration will bring you to rest right at the intersection? how long does it take you to stop after the light changes? the known values: vi=20m/s xi=110m t=.50s vf=0m/s xf=0m a=?
