A book with a mass of 5 kg is pushed off a table with the velocity of 2 m/s. What is its momentum? A. 7 kg-m/s
B. 3 kg-m/s
C. 15 kg-m/s
D. 10 kg-m/s

Answers

The momentum of a book with a mass of 5 kg is pushed off a table with a velocity of 2 m/s is option D. 10 kg-m/s.

What is momentum?

Momentum is the quantity of motion of a moving body, measured as a product of its mass and velocity.
It is the vector quantity. It has both magnitude and direction.
In the International System of Units, the unit of measurement of momentum is Kg*m/s.

What is the momentum of a book with a mass of 5 kg is pushed off a table with a velocity of 2 m/s?

Formula of momentum = p = mv

Here,

p = momentum

m = mass

v = velocity

Here the given mass is 5 and velocity is 2. then,

p = mv

=5×2

=10 Kg*m/s

Hence, the momentum of a book with a mass of 5 kg is pushed off a table with a velocity of 2 m/s is option D. 10 kg-m/s.

How does the sun cause wind?

Answers

wind is caused by a difference in pressure from one area to another area on the surface of the earth. Air naturally moves from high to low pressure, and when it does, it is called wind. Generally, we can say that the cause of wind is the uneven heating of the earth's surface by the sun.
