A block of mass m = 2.02 kg slides down a 30.8 ° incline which is h = 3.46 m high. At the bottom, it strikes a block of mass M = 6.90 kg which is at rest on a horizontal surface. (Assume a smooth transition at the bottom of the incline.) If the collision is perfectly elastic, and friction can be ignored, determine the speed of the smaller block and larger box after the collision.

How would you determine the answer?

If so, what is it? And what does this have to do with unpaired valence electrons?

Also, make this applicable to nitrates. I know if it is a main group cation, it will be colorless or white. I know if it is a transition metal, it will be colored. But why? try to answer this by telling me about UNPAIRED VALENCE ELECTRONS
