Question

Please answer this question for 20 point... What is the momentum of 1000-kg car moving northward at 20 m/s?

Answer 1

Answer:

Formula for the momentum it is momentum=velocity*mass

We know masz and velociti. Its in correct units, so we just have to substitute our data to formula.

momentum=1000kg*20m/s=20 000 \frac{kg*m}{s}

Answer 2

Given:

• Velocity of car = 20 m/s towards North.
• Mass of car = 1000 kg.

To find:

• Momentum of the car ?

Calculation:

• Momentum is a vector quantity characterized by the product of mass and velocity vector.

• Direction of momentum will be towards the direction of velocity vector.

Let momentum be P :

$P = mass \times velocity$

$\implies \: P = m \times v$

$\implies \: P = 1000 \times 20$

$\implies \: P = 20000 \: kg \: m {s}^{ - 1}$

• The direction of the momentum will be towards North.

So, momentum of the car is 20000 kg m/s and towards North.
