Can Anyone Help Me With This Physics Problem??

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.

Please help with any advice on how to solve this problem. It seems like there is not enough information to go on.

The numbers 2, 3, 5, 7, and 13 are placed on a number line. For any integer x, its "remoteness" is the sum of the squares of its distance to each of the five numbers. For example, the remoteness of 10 is 8² + 7² + 5² + 3² + 3² = 156. What integer has the smallest remoteness?

I need some help here, any help would be freakin sweet. This is on my biology take home test. Its pretty dumb and random, but here it goes...
If you have a loaded pizza and an ice cream float for lunch, each of the five kingdoms is represented either as an ingredient or in production or processing of an ingredient. List the 5 kingdoms and identify at least one ingredient with each kingdom. (I think) The five kingdoms are plant, animal, fungi, protista, and prokaryotic.

On an SAT math section. There was a question like this:
If the sum of all lengths of a cube is 8 what is the volume of the cube?
so I drew the cube and there was 4 lengths so I divided
8/4=2 therefore the length=2 and the width=2 and height=2 since Volume of a cube is =lwh.
My answer was 8. was i correct?

b) Tap water contains 1% salt and 99% water.
c) Salt water contains 6% salt and 94% water.
d) Salt water has a higher concentration of salt than fresh water or Elodea cells.

Answer the following questions using the information above about the cell in tap water:
1) What is the percentage of water outside the cell?
2) What is the percentage of water inside the cell?
3) How do the percentages compare?
4) WOuld the cell shape change once it was placed in the tap water?

THANK YOU SOOOO MUCHHH! MAY ALL YOUR WISHES COME TRUE!
