Newton's Law.
- First law: When viewed in an intertial reference frane, an object either is at rest or moves at a constant velocity , unless acted upon by an external froce .
- Second law: The acceleration of a body is directly proportional to, and in the same direction as, the net force acting on the body, and inversely proportional to its mass.
- Third law: When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction to that of the first body.

A car and a truck have a collision The truck has a mass 8 times the mass of the car if the truck is moving at 60kmhr and the car is stationary how fast do the two move after their inelastic 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 a train car moving down a track at 10 ms hits another train car that is not moving Explain how momentum is conserved after the collision?
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.
When moving freight car collides with an identical one that is at rest. If momentum is conserved what happens to the second car after the collision?
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.
What is a secondary collision?
When a vehicle is in a car accident there can be a secondary collision. For example, if car ÒbÓ was rear ended that is the first collision but when that car hit the car in front of them that is the secondary collision.
Explain how momentum is conserved when a car hits a bicycle?
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.
The moral principle is involve when a car driver who is involve in an accident is changed reckless in prudence causing damage of property?
Recklessness may constitute an offense against property.
What is a secondary?
When a vehicle is in a car accident there can be a secondary collision. For example, if car ÒbÓ was rear ended that is the first collision but when that car hit the car in front of them that is the secondary collision.
What is collision in car insurance?
Collision is a slang term for coverage on your car if you cause the accident.
In an isolated system two cars each with a mass of 2500 kg c ollide Car 1 is initially at rest while Car 2 was moving at 20 m's What is their speed after the collision?
The speed of each car after the collision depends on how the collision occurs. If it is an elastic collision, both cars will move with different speeds, determined by the conservation of momentum and kinetic energy principles. If it is an inelastic collision, the cars will move together at a speed determined by the conservation of momentum principle. More information is needed to calculate the final speeds accurately.
When a car is hit in a parking lot is it a comprehensive or collision claim?
Collision generally covers you in collisions with other cars or property; comprehensive generally covers you in accidents that don't involve other cars, such as animal hits, weather-related losses, and theft or vandalism. So you are covered under collision coverage !
In an isolated system two car each with a mass of 1000 kg collide Car 1 is initially at rest while Car 2 was moving at 10 ms They move off together What is their speed?
Their speed after the collision can be calculated using the principle of conservation of momentum. The total momentum before the collision (0 for Car 1 and 10000 kg*m/s for Car 2) is equal to the total momentum after the collision (final speed * total mass). By solving for the final speed, you can find that their speed after the collision will be 5 m/s.
Does Geico offer Illinois collision car insurance?
Yes Geico offers collision car insurance Geico Collision coverage pays for damage to your car when your car hits, or is hit by, another vehicle or other object.
