Analysis of Auto Accident: Speed Calculation and Collision Explanation
Auto Accident Analysis
Calculating Car A's Speed
- (a) What was the speed of car A just before the collision? The speed of car A just before the collision can be calculated using the law of conservation of momentum and the work-energy principle. The speed is determined to be 51.58 mph.
- (b) Was car A speeding with a speed limit of 35 mph, and if so, by how many miles per hour? With the given speed limit of 35 miles per hour, car A was exceeding the speed limit by 16.58 mph.
Explanation of Collision
Collision is defined as the event when two objects strike each other from either direction. During a collision, the speed of colliding objects may vary according to the direction of the approach. The key data provided for the analysis:- The mass of car A: 1500 kg
- The mass of car B: 2100 kg
- The length of the skid mark: 7.30 m
- The coefficient of kinetic friction between tires and road: 0.65
