Suppose there's a car accident in which a pedestrian (let's call him Paolo) is hit by a car and thrown into the air. Paolo is injured but he will be okay. Based on where Paolo landed, police accident investigators would like to know how fast the car was going when it hit him, as part of the for determining who was at fault. process 1. In 1983, John and Angela Searle published a paper at the Stapp Car Crash Conference which including the following formula: V2ugs cos (8) + u sin(0) Here v is the velocity of the car, g is acceleration due to gravity, u is the coefficient of friction (more on this later), s is the distance traveled by the pedestrian, and 0 is the initial angle of the hit pedestrian. The paper included this slightly disturbing image: END PONT 1) BOUNCING SLIGING FISURE 5 FLIGT OF A PROJECTILE OVER A ROUGH PLANE 0.66, g 9.81m/s2, s = 100rm, and 0 = 0.5 radians. Let's use metric units. Suppose = What was the velocity of the car?
