What angle does the Blue ball go off on after the collision? (measured off it's original direction (x-direction)) Estimate: In the current setup, how fast would the Blue ball need to be going initially to come off at an angle of 5 degrees?

An oatmeal cookie is dropped on the floor. Is this an inelastic collision? Why or why not? It is because the cookie and floor can be considered one object. It is because the cookie and floor are stuck together. It is not because there is not momentum involved. It is not because the cookie and floor do not move away together as a unit.

A bullet of a mass 5.00g is fired horizontally into a stationary wood block of a mass 0.450kg. After impact the block with the embedded bullet is moved horizontally at 6.2 m/s A) what is the initial speed of the bullet B) what is the average force during the collision if it lasted for 0.23* 10^(-3) s

When two object collide in an isolated system, the forces that act on each object at the moment of collision are __________.   Group of answer choices greater on the object with less initial momentum greater on the object traveling the slowest greater on the object traveling the fastest equal and opposite greater on the object with more initial momentum greater on the more massive object greater on the less massive object

A single stationary railway car is bumped by a five‑car train moving at 9.3 km/h. The six cars move off together after the collision. Assuming that the masses of all the railway cars are the same, then the speed of the new six‑car train immediately after impact is
