Total momentum
In a two-car collision, the total angular momentum is conserved only if no external torque is acting on the system. If there is no net external torque exerted on the cars during the collision, the total angular momentum before the collision will be equal to the total angular momentum after the collision.
When a car hits a bicycle, momentum is conserved because the total momentum of the system (car + bicycle) before the collision is equal to the total momentum after the collision. This means that the combined momentum of the car and bicycle remains constant despite the collision, with some of the momentum transferring between the two objects during the impact.
If momentum is conserved, the second car will start moving in the opposite direction with the same speed and momentum as the first car after the collision. This is due to the principle of conservation of momentum, which states that the total momentum of an isolated system remains constant before and after a collision.
I will assume that the collision is completely inelastic (that is, the truck and the car coalesce, moving off with the same velocity after the collision). This assumption is crucial as without it, the question cannot be solved if the inelastic collision is maintained.Let the mass of the car be m. The mass of the truck is 8m.From the principle of conservation of momentum;8m(60) = (8m + m)vwhere v is the final velocity.So, v = 8(60)/9v = 53.3 km/h
Suppose that 1st car is X-car and the 2nd car is Y-car. Answer: After the collision, car X is no linger moving, but car Y is moving.
The second car will begin to move in the same direction as the first car after the collision, with a speed that depends on the masses and velocities of the two cars before the collision. Momentum conservation ensures that the total momentum of the system remains constant.
That simply means that the total momentum before and after the crash is the same. Please bear in mind that momentum is a vector quantity. Thus, for example, one car moving at 20 m/s (that's 72 km/hour) north, and another car (same mass) that moves at 20 m/s south have a total momentum of zero, because of the way vectors are added.
In an elastic collision, kinetic energy is conserved and momentum is conserved. Both objects bounce off each other after the collision. In an inelastic collision, kinetic energy is not conserved, but momentum is conserved. The objects stick together or deform after the collision.

A Lot!
In a car and ten-wheeler truck collision, occupants of the car are more likely to be injured due to the size and weight disparity between the vehicles. The occupants of the car are at a higher risk of injury due to the impact force generated by the larger and heavier truck.
A recovery truck(also know as 'tow truck')is basically a vehicle used to transport a disabled car, truck etc., from one location to another. They are used for clearing accident and collision debris...
