Doc Al said:The way we work on this forum is that you give it a shot, showing what you did and where you got stuck. And we then help you out. (Trust me, you'll get much more out if it that way.)
This is an example of an inelastic collision. Look it up in your text. You may find this helpful: https://www.physicsforums.com/showpost.php?p=2157983&postcount=5"
Good! That's the right formula.BobbyTee said:Ok so I used the M1xV1 + M2xV2 = (M1+M2)V Formula.
What you're doing wrong is not taking direction into account. Momentum and velocity are vectors, so direction counts. The way you include direction is by using an appropriate sign for the velocities. For example: Use + to represent East and - to represent West.21.48x + (1386.25x32.07) = 8.38(1386.25+x)

Good!BobbyTee said:Ok, did it again with the correct signs and I got 1099.81 Kg. Correct?
Exactly.And what if the direction is north or south?
North = + and South = -?
To calculate the mass of a car involved in a collision, you will need to know the velocity and momentum of the car before and after the collision. The mass can be calculated using the equation m = p/v, where m is the mass, p is the momentum, and v is the velocity.
The mass of a car in a collision is affected by several factors, including the weight of the car, the speed of the car, and the direction and type of collision. The mass can also be affected by any additional objects or passengers in the car at the time of the collision.
The mass of a car plays a significant role in the severity of a collision. A heavier car will have more momentum and will cause more damage in a collision compared to a lighter car. This is why it is important to consider the mass of a car when looking at safety ratings.
Yes, it is possible to calculate the mass of a car involved in a collision if you know the force of impact. You can use the formula m = F/a, where m is the mass, F is the force, and a is the acceleration. However, this calculation may not be accurate as it assumes a constant acceleration, which is not always the case in a collision.
Knowing the mass of a car can provide valuable information in understanding the cause of a collision. For example, if a smaller car is hit by a larger car, the force of the impact will be greater on the smaller car due to the difference in mass. This can help determine which car was at fault in the collision and can also help in making safety improvements to prevent similar collisions in the future.
