Walking in Waikiki, a tourist steps out onto Kuhio Dr while texting. Unbeknownst to the sunburned visitor, the street has been closed for the filming of a car chase scene for Hawaii 5-0. Slamming on the breaks, the stunt driver is thrown against his seatbelt, stopping in 90m. If the driver and the car weigh a total of 544kg and were traveling at 18 m/s, what force does the 90kg driver feel?

Static and Kinetic Friction

Kinetic friction comes into existence when there are moving surfaces means in other words we can say that the force which comes into existing between moving surfaces is known as kinetic friction.
