(a) If the system's kinetic energy, as measured from the Earth reference frame, decreases by 20% because of the collision, what are the final velocities of the balls?
(b) What change in internal energy has occurred?
(c) An observer watches this collision from a reference frame moving at a velocity of 15 m/ s to the east relative to the Earth reference frame. What changes in kinetic energy does this observer measure?
A neutron with mass m1 moving with velocity v0 collides elastically and head-on with a target particle with mass m2 that is at rest. After the collision, the neutron moves with velocity v1f and the target particle moves with velocity v2f.
Write the two equations that express conservation of momentum and conservation of kinetic energy for this collision.
Consider collisions of the neutron (mass = 1.0 atomic mass unit (amu)) with the following stationary target particles
an electron (mass =5 x 10-4 amu)
a proton (mass = 1.0 amu)
the nucleus of a carbon atom (mass = 12.0 amu)
the nucleus of a uranium atom (mass = 238 amu)
Match some of the collisions above with each of the following head-on collisions that we discussed in lecture:
the collision between two billiard balls, one of the billiard balls initially at rest
the collision between a ping pong ball and a bowling ball, the ping pong ball initially at rest
the collision between a ping pong ball and a bowling ball, the bowling…
