A 8000 kg car heading north collides at an intersection with a 12,000 kg truck heading west. If they lock together and travel at 30 m/s at 28° north of west just after the collision, how fast was the west bound car initially traveling?
Homework Answers
By Conservation of momentum in x-direction
-MtruckVtruck=(Mcar+Mtruck)(-VCos28)
12000*Vtruck=(8000+12000)(30Cos28)
Vtruck= 44.147 m/s

A 1200·kg car traveling with a velocity of 12·m/s north collides head-on with a 2400·kg truck traveling with a velocity of 8·m/s south. Immediately after the collision, the velocity of the car is 4·m/s south. Take north as the positive direction (a) What is the velocity of the truck immediately after the collision? (b) What impluse is delivered to the car by the truck? (c) What impluse is delivered to the truck by the car?

Two cars approach an ice-covered intersection. One car, of mass 1.25 103 kg, is initially traveling north at 11.1 m/s. The other car, of mass 1.58 103 kg, is initially traveling east at 11.1 m/s. The cars reach the intersection at the same instant, collide, and move off coupled together. Find the velocity of the center of mass of the two-car system just after the collision. Please provide magnitude & direction (ex - 30 degrees North of West)

A 1000-kg car moving at 30m/s due north collides completely elastically with a 1250-kg truck heading north of east. After the collision the truck is moving due north and the car is moving due east. Find the initial speed of the truck. I think the answer is 34m/s and we have to break it up into x and y component and equate them but please tell me the theory behind it. Thanks

A small compact car with a mass of 1000 kg is traveling north towards an intersection at a speed of 15 m/s. A truck with a mass of 2000 kg is traveling east at 10 m/s on the cross street approaching the same intersection. The two vehicles collide and stick together. a. What is the magnitude and direction of the velocity of both vehicles after the collision? b. How much energy was lost during the collision?

Two cars approach an ice-covered intersection. One car, of mass 1.11*103 kg, is initially traveling north at 12.1 m/s. The other car, of mass 1.70*103 kg, is initially traveling east at 12.1 m/s. The cars reach the intersection at the same instant, collide, and move off coupled together. Find the velocity of the center of mass of the two-car system just after the collision. Magnitude= Directions = North of East

A car with a mass of 980 kg is initially traveling east toward
an intersection with a speed of vc = 20.9 m/s and a 1500 kg pickup
is traveling north toward the same intersection. The car and truck
