Answer:
Speed of larger piece is 
Explanation:
We apply the principle of conservation of momentum.
The watermelon is initially at rest. The initial momentum = 0 kg m/s in all directions.
After the collision,
Vertical momentum = momentum of piece in y-direction + y-component of momentum of larger piece = 
Here,
is the y-component of velocity of larger piece.
This is equal to 0, since the initial momentum is 0.

Horizontal momentum = momentum of piece in x-direction + x-component of momentum of larger piece = 
Here,
is the x-component of velocity of larger piece.
This is also equal to 0, since the initial momentum is 0.

The velocity of the larger piece,
, is the resultant of
and
. Since they are mutually perpendicular,


I think with the increasing of temperatures of earths oceans and atmosphere is causing climate change and global warming. When the ocean heats up a lot of sea animals die and with the hot temps in the atmosphere is causing rare hot tempatures in some places in the world.
It can cause some intense storms but it mostly heats up the world and cause a lot of problems.
I hope i answered your question right.
Answer:
you need to consider the use for the product, how brittle the materials are, how they react to certain things, the cost of the materials, the durability and flexibility of the materials, and how easy to obtain the materials are as well as how they would work and how they would hold
