Answer:
Explanation:
Applying conservation of momentum
mA v0 + 0 = mA x 12v0 + mB x 92v0
11 mA = - 92mB .
mA / mB = 92 / 11
mA : mB = 92 : 11.
Answer:
The first law - The first law states that any object in motion will continue to move in the same direction and speed unless other forces act on it. For an example an apple starts rolling without any other forces interrupting it will roll forever.
The Second law - The second law says that the greater the mass of an object, the more force it will take to accelerate the object.
And lastly The Third law - "For every action, there is an equal and opposite reaction."

Answer:
potential energy
kinetic energy
thermal energy
Explanation:
The book's potential energy can be released by knocking it off the table. As the book falls, its potential energy is converted to kinetic energy. When the book hits the floor this kinetic energy is converted into heat and sound by the impact.
Answer:
The work done is 0.
Explanation:
The reason no work is done is because the equation W = Fs.
W = work
F= force
s= displacement
In this scenario F = 50 and s= 0
Therefore.
W = 50(0)
W = 0
