An automobile has a mass of 2300 kg and a velocity of positive 16 m/s. It makes a rear end collision with a stationary car whose mass is 1800 kg. The cars locked 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, magnitude and direction, the acts on the skidding cars from just after the collision until they come to a halt. C) if the coefficient of kinetic friction between the wheels of the cars and the pavement is 0.80, determine how far the cars skid before coming to rest

A 930 kg sports car collides into the rear end of a 2300 kg SUV stopped at a red light. The bumpers lock, the brakes are locked, and the two cars skid forward 3.1 m before stopping. The police officer, knowing that the coefficient of kinetic friction between tires and road is 0.80, calculates the speed of the sports car at impact. What was that speed?

You have been hired as an expert witness in a court case involving an automobile accident. The accident involved a car of mass 1910 kg (car A) which approached a stationary car of mass 1000 kg (car B). The driver of car A applied his brakes 13 m before he crashed into car B. After the collision, car A slid 17 m while car B slid 30 m. The coefficient of kinetic friction between the locked wheels and the road...

A block of mass m1 = 1.20 kg moving at v1 = 1.20 m/s undergoes a completely inelastic collision with a stationary block of mass m2 = 0.500 kg . The blocks then move, stuck together, at speed v2. After a short time, the two-block system collides inelastically with a third block, of mass m3 = 2.60 kg , which is initially at rest. The three blocks then move, stuck together, with speed v3. Assume that the blocks slide without...
