You have been called to testify as an expert witness in a trial involving a head-on collision. Car A weighs 1515 lb and was traveling eastward. Car B weighs 1125 lb and was traveling westward at 44.0 mph. The cars locked bumpers and slid eastward with their wheels locked for 20.5 ft before stopping. You have measured the coefficient of kinetic friction between the tires and the pavement to be 0.750. How fast (in miles per hour) was car A...

A 2000 kg Cadillac had just started its march from a stop sign when it was struck from behind by a 1000 kg Volkswagen. The bumpers locked and the two cars slid together until they stopped. Officer Tom, responding to the accident, measured that skid marks were 3.0 m long. The driver also testified that the speed of the Cadillac just before the impact was 5.0 m / s. Officer Tom accused the Volkswagen of driving recklessly. Should the Volkswagen...

You are an insurance investigator trying to figure out if a driver making an insurance claim was exceeding the speed limit before a collision. Driver A has a car of mass mA, which slammed into Car B (mass mB) which was at rest at a stop sign before the collision. The two cars locked their bumpers during the collision. From the damage, you estimate that the collision speed was v_hit. You can tell from marks at the scene of the...

A 920-kg sports car collides into the rear end of a 2100-kg SUV stopped at a red light on a flat dry level road. The bumpers lock, the brakes are locked, and the two cars skid forward 4.0 m before stopping. The police officer on scene, using her SmartPhone, looks up the coefficient of kinetic friction between rubber tires and concrete road as 0.80, she then calculates the speed of the sports car at impact. What was that speed?

Chapter 07, Problem X11 An automobile has a mass of 1760 kg and a velocity of 20.2 m/s. It makes a rear-end collision with a stationary car whose mass is 2100 kg. The cars lock bumpers and skid off together with the wheels locked. (a) What is the velocity of the two cars just after the collision? (b) Find the impulse that acts on the skidding cars from just after the collision until they come to a halt. (c) If...

91: (12.5 points) Two cars of the same mass run head-on into each other at C. After the collision, the car skid with their brakes locked and come to a stop in the positions shown in the lower part of the figure. Knowing that the speed of the car A just before the impact was 8 km/hr and that the coefficient of kinetic friction between the pavement and the tires of both cars is 0.30, determine (a) the speed of...
