That's going to depend on the directions of each of the two initial velocities.
It's also going to depend on who measured the initial velocities, where he
was standing, how he was moving, and with respect to what else, etc.
That may vary, depending on the initial velocity and mass.That may vary, depending on the initial velocity and mass.That may vary, depending on the initial velocity and mass.That may vary, depending on the initial velocity and mass.
If initial velocity is zero, the collision seems unlikely.
Distance is a measure of separation of bodies in space. It is also the separation of two places on the surface of a body.
To find the change in velocity in a given scenario, subtract the initial velocity from the final velocity. The change in velocity is the difference between the two velocities.
To find acceleration, you take Vi [Initial Velocity] and you subtract if from Vf [Final Velocity.] (Vi - Vf) If they Vi and Vf are already given, you take the two givens and you subtract them from each other. Vi minus Vf. Do not do Vf minus Vi or it will be wrong. After you do that, you divide your answer from T [Time] (Vi - Vf) a= _____ t Once you get your answer, that will be your acceleration.
There are two methods, it depends on what variables you have: 1. Subtract the initial velocity from the final velocity and divide that whole term by the time (Vf- Vi)/t = a 2. Square both the initial velocity and the final velocity and subtract the squared inital velocity from the squared final velocity and that answer by two times the distance (Vf^2 - Vi^2)/2d = a
The change in velocity is 15 m/s left.
they both crash
An "instant center" (IC) is a point that instantaneously has the same velocity in two bodies.
Yes it can be!!! If two cars on a straight road head directly toward each other at a speed of 60mph (relative to the road), the velocity of one relative to the other is 120mph. This example arbitrarily uses the road as the reference for each car's speed, but there really is no such thing as "absolute velocity" and both cars would have a velocity of about 1000mph relative to the center of the Earth. According to Einstein's principles of "Relativity" all velocity is relative.
You can only know the distance for sure if acceleration or deceleration is constant. Add the start and end velocities and divide by two and then multiply by the time to get your distance.
There are several layers of complexity to resultant velocity of a colision based on the assumptions used. In a cohessive colision, two or more bodies colide and fuse into one. The resultant velocity is the speed and direction the new body will travel due to the momentum of the original bodies. In a non-cohessive colision, two or more bodies colide, but subsequently rebound away from each other based on the area of contact and momentum of the relevant bodies. The resultant velocities are the speed, direction, and rotation the bodies after the crash.
