To solve this problem we will apply the momentum conservation theorem, that is, the initial momentum of the bodies must be the same final momentum of the bodies. The value that will be obtained will be a vector value of the final speed of which the magnitude will be found later. Our values are given as,
Using conservation of momentum,
Solving for
Using the properties of vectors to find the magnitude we have,
Therefore the magnitude of the velocity of the wreckage of the two cars immediately after the collision is 12.4135m/s
Answer:
1. distance and period of time.
Explanation:
The speed is calculated using the formula
"k" is the speed, "d" is the distance and "t" is the time.
You need distance and time to calculate the speed.
Speed is how fast an object is going. The direction is irrelevant to speed, not to be confused with velocity, which is speed in a given direction.
