A series resistive circuit has two resistors. R1 is 580 ohms. The total circuit current is 76.9 milliamps. The source voltage is 130 volts.
Find the voltage drop across R1 in volts (with at least one digit to the right of the decimal).

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=?
