Please help me solve this physics question?
You arrive at the scene of a car accident and asked to determine what, if any, car was speeding. immediately begin gathering information. The accident occurred on dry concrete and car tires are made of rubber. The coefficient of kinetic friction is 0.68. The first car, a 2006 Cadillac Escapade, approached from the north while the other, a Honda Accord Hybrid 2007, came from the West. The two cars stuck together and produce a drag mark 66 degrees south of east (294 degrees). The length is 13.9 Skidmark million. According to the manual inside the cars, the Honda has a mass of 1640kg, while the Cadillac has a mass of 2675kg. Each car in an area of 30 miles per hour at the time of the accident. A mile is 1.6 kilometers. If a driver is issued a ticket for speeding? Be solved mathematically.
Wow, large amount of data to work through. We need the total mass velocity at impact. The total mass M = 4315 kg. The friction force F = M * a * k = 4315 kg * 9.8 m / s ^ 2 * 0.68 = 28755.16 N and deceleration is 9.8 * 0.68 = 6.664 m / s ^ 2 with the distance (13.9 million) and the deceleration time is known : s = 0.5 * a * t ^ 2 = 13.9 = 3.332 * t ^ 2 t = sqrt (13.9/3.332) = 2.04 s Now we know that the rate of MV = a * t = 6.664 * 2.04 = 13.61 m / s, and the combined momentum is MV = 4315 * 13.61 = 58.731 kg.m / s for the Caddy m1v1 = v1 = 2675 * MV * sin66 = 58 731 * 0.91 = 53,654 for v1 = 53654/2675 = 20.1 m / s for the Honda m2v2 = v2 = 1640 * MV * cos66 = 58.731 * 0.41 = 23.888 for v2 = 23888/1640 = 14.6 m / s Since the speeds are well below 30 mph = 48 km / h, no tickets were issued.
