Two identical cars each of mass 1.8 metric tons, collide head-on during a crash-test. One car was moving at speed 52 mi/hr before the collision, the other car was moving at 66 mi/hr. After the collision, the two cars skid together until they come to rest. What was the total impulse magnitude exerted by friction on the cars after the collision?

Consider the same situation as before, only after the crash, the cars skid for a short distance before ending up on an oil slick and sliding approximately frictionlessly with a final speed of 3 mi/hr. What was the impulse magnitude exerted on the two cars by friction while they were skidding, up until they reached the oil slick?

Two cars collide in an intersection: a 2200kg SUV that had been headed East and a 1500kg sports car that had been headed North. The cars deformed and remained together after colliding, sliding to rest 5.0m from the crash. The angle from the crash to the resting point is 35o N of E. Coefficient of sliding (kinetic) friction is μ=0.80 for both vehicles. There are 8m long skid marks leading into the intersection indicating that the northbound car locked its...

Two cars arriving at a T-intersection crash with each other. The first car has a mass of 1320kg and was traveling east at 80.0 km/h, the second car has a mass of 1740kg and was traveling north at 65.0km/h. If the collision is completely inelastic. with what speed are the wrecks moving after the collision and in which direction? You can ignore the effect of friction forces between the road and the cars during the collision.

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)...

Two cars collide at an intersection. Car A, with a mass of 2000 kg , is going from west to east, while car B , of mass 1300 kg , is going from north to south at 12 m/s . As a result of this collision, the two cars become enmeshed and move as one afterward. In your role as an expert witness, you inspect the scene and determine that, after the collision, the enmeshed cars moved at an angle...

Two cars, both of mass m, collide and stick together. Prior to the collision, one car had been traveling north at speed 3v, while the second was traveling at speed 2v at an angle ? south of east (as indicated in the figure). After the collision, the two-car system travels at speed vfinal at an angle ? east of north. (Figure 1) Find the speed vfinal of the joined cars after the collision. Express your answer in terms of v...
