Constant Velocity: Collision Imminent.
If we want to know the velocity of the train with respect to the car, we need to take the car as a stationary object. Let's imagine riding in the ca
This is an inelastic collision, so we use conservation of momentum:
mv + 0 = (m+m)vf
vf = v/2
Explanation:
There are two useful equations here:
(v1-v2) = -(v1 v2)
(the relative velocity in an elastic collision is
equal and opposite before and after)
And
m

Two points are on a disk that is turning about a fixed-axis through its
center, perpendicular to the disk and through its center, at increasing angular
velocity. One point on the rim and the other point is halfway
