Car-Minivan Collision: Final Velocity Vector

In summary, the problem involves a collision between a car and a minivan, where both vehicles are stuck together after the collision. The final velocity vector of the combined car and minivan can be determined by using the conservation of momentum principle. The car has a mass of 1000 kg and a velocity of 15m/s east, while the minivan has a mass of 1200 kg and a velocity of 20m/s north. After the collision, the final velocity can be calculated to be 17.72 m/s. However, further steps are needed to determine the direction of the final velocity.

Homework Statement


A car with a mass of 1000 kg traveling with a velocity of 15m/s east collides with a 1200 kg minivan traveling at a velocity of 20m/s north. After the collision the car and the minivan are stuck together. Draw to the scale the final velocity vector of the car and minivan after the crash.
so like how would i set this up?

Homework Equations


I got the answer of 17.72 for velocity. But i don't know what to take on after this step. Is this the final velocity?

The Attempt at a Solution


Ptotal/mass = velocity

Welcome to PF,

Have you tried to use conservation of momentum?

(In future, post your attempt at the problem together with its statement. The rule at PF is that no help should be provided if no attempt is shown.)

Think about what vector property of the cars that are conserved in the (in-elastic) collision and how you may draw these vectors in a diagram.

FAQ: Car-Minivan Collision: Final Velocity Vector

What is a car-minivan collision?

A car-minivan collision is an event where a car and a minivan collide with each other, resulting in a force exerted on both vehicles.

How is the final velocity vector of a car-minivan collision determined?

The final velocity vector of a car-minivan collision is determined by taking into account the initial velocity of the car and minivan, the mass and direction of each vehicle, and the force of impact.

What factors influence the final velocity vector of a car-minivan collision?

The final velocity vector of a car-minivan collision is influenced by factors such as the speed and direction of each vehicle, the mass and size of each vehicle, and the angle of impact.

Can the final velocity vector of a car-minivan collision be predicted accurately?

While the final velocity vector of a car-minivan collision can be calculated using mathematical equations, it may not always accurately predict the exact outcome of the collision as it is also affected by external factors such as road conditions and reaction time of the drivers.

How can the impact of a car-minivan collision be minimized?

The impact of a car-minivan collision can be minimized by following traffic laws and regulations, maintaining a safe distance from other vehicles, and adhering to safe driving practices such as avoiding distractions and driving at a safe speed.
