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?

5. A runaway truck with a mass of 2100 kg strikes a car of mass 1350 kg, which was at rest before the collision. The car’s wheels are locked during the entire event, but the truck has no brakes, i.e., it is rolling freely on the road. The two vehicles move forward together, and the car’s tires leave skid marks for a distance of 1.5 m. Suppose that the coefficient of kinetic friction between the car’s tires and the road...

A 831 kg car stopped at an intersection is rear-ended by a 1830 kg truck moving with a speed of 14.5 m/s. If the car was in neutral and its brakes were off, so that the collision is approximately elastic, find the final speed of both vehicles after the collision. speed of car in m/s speed of truck in m/s

You are called as an expert witness to analyze the following auto accident: Car B, of mass 1900 kg, was stopped at a red light when it was hit from behind by car A, of mass 1500 kg. The cars locked bumpers during the collision and slid to a slop with brakes locked on all wheels. Measurements of the skid marks left by the tires showed them...

A 1050-kg sports car is moving westbound at 15.0 m/s on a level road when it collides with a 6320-kg truck driving east on the same road at 10.0 m/s. The two vehicles remain locked together after the collision. (a) What is the velocity (magnitude and direction) of the two vehicles just after the collision? (b) At what speed should the truck have been moving so that it and the car are both stopped in the collision? (c) Find the...
