Chapter 6, Problem 52P

Two automobiles of equal mass approach an intersection. One vehicle is traveling with velocity 13.0 m/s toward the east, and the other is traveling north with velocity v2i. Neither driver sees the other. The vehicles collide in the intersection and stick together, leaving parallel skid marks at an angle of 55.0° north of east The speed limit for both roads is 35 mi/h, and the driver of the northward-moving vehicle claims he was within the limit when the collision occurred. Is he telling the truth?

‏Two trucks of the same mass approach a traffic signal . Truck A travels northward at 22.7 m / s and truck B travels eastward . They collide and stick together , traveling at 32 ° north of east . What was the initial velocity of truck B ?
Two bumper cars at the county fair are sliding toward one another (see figure below). Initially, bumper car 1 is traveling to the east at 5.85 m/s, and bumper car 2 is traveling 78.8° south of west at 4.05 m/s. They collide and stick together, as the driver of one car reaches out and grabs hold of the other driver. The two bumper cars move off together after the collision, and friction is negligible between the cars and the ground.

Two bumper cars at the county fair are sliding toward one another (see figure below). Initially, bumper car 1 is traveling to the east at 5.62 m/s, and bumper car 2 is traveling 60.0° south of west at 10.00 m/s. After they collide, bumper car 1 is observed to be traveling to the west with a speed of 3.28 m/s. Friction is negligible between the cars and the ground.   (a) If the masses of bumper cars 1 and 2 are 584 kg and 615 kg respectively, what is the velocity of bumper car 2 immediately after the collision? (Express your answer in vector form. Enter your answer to at least three significant figures.) v2 =         m/s? (b) What is the kinetic energy lost in the collision?(in joules)
