Acar of mass 1330 kg is traveling at 28.0 m/s. the driver applies the brakes to bring the car to rest in 5.6 s. calculate the force of the brakes on the car.

Agalvanometer has an internal resistance of 100 ω and deflects full-scale at 2.00 ma. what size resistor should be added to the galvanometer to convert it to a milliammeter capable of reading up to 4.00 ma, and how should this resistor be connected to the galvanometer?
