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?
