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?

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 blue car with mass mc = 481 kg is moving east with a speed of vc = 23 m/s and collides with a purple truck with mass mt = 1289 kg that is moving south with a speed of vt = 10 m/s . The two collide and lock together after the collision. *What is the magnitude of the initial momentum of the car? *What is the magnitude of the initial momentum of the truck? *What is the magnitude...
In a crash test, a car with a mass of 1500 kg is initially moving at...
In a crash test, a car with a mass of 1500 kg is initially moving at a speed of 18 m/s just before it collides with a barrier. The final speed of the car after the collision is zero. The original length of the car is 4.48 m, but after the collision, the smashed car is only 3.86 m long. Making the very rough approximation that the large force that the barrier exerts on the car is approximately constant during...

A car of mass 2400 kg collides with a truck of mass 4500 kg at the intersection of horizontal roads. The vehicles stick together and slide immediately after the collision. The x- and y-components of the car’s velocity just before the collision are (36, 0) m/s, respectively, and the same components of the truck’s velocity just before the collision are (-15, 25) m/s. a. calculate the x component of the velocity of the combined car and truck immediately after the...

The driver of one car has a mass of 1200 kg and is traveling at 10 m/s westward when he collides with another car with a mass of 2000 kg that is traveling 15 m/s northward. The two cars stick together after colliding. Please show all work. a) What is the total momentum before the collision and after the collision? b) What are the speed and direction of the cars after the collision? c) If coefficient of kinetic friction between...

A hockey puck, mass 0.24 kg, travelling with a speed of +20 m/s. collides with another stationary puck of exactly half the mass, hitting it head-on, but instant superglue makes the pucks stick together. The collision is perfectly inelastic and one dimensional. Ignore any friction with the ice they are travelling on. Calculate the total momentum of the two-puck system both before and after the collision.

In a crash test, a car with a mass of 1600 kg is initially moving at a speed of 18 m/s just before it collides with a barrier. The final speed of the car after the collision is zero. The original length of the car is 3.80 m , but after the collision, the smashed car is only 3.23 m long Part 1: What is the average speed of the car during the period from first contact with the barrier...
