A6 kg object (a), moving at 3 m/s, collides with a 6 kg object (b), which is at rest. after their collision, object a moves off in a direction 40 deg to the left of its original direction. object b moves off in a direction 50 deg to the right of object a's direction.

a. draw a vector diagram and determine the momenta of objects a and b following the collision
b. what is the velocity of each object after the collision

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
