2. What is the mass of a car with a momentum of 10,000.00 kgm/s, traveling at 15.0 m/s?

Svetradugi [14.3K]

Answer:

666.67 kg is the mass of a car.

Explanation:

Momentum is defined as amount of motion possessed by the the moving body. It is mathematically calculated by multiplying mass into velocity by which object is moving.

$Momentum(P)=Mass(m)\times Velocity(v)$

Mass of the car = m =?

Velocity of the car = v = 15.0 m/s

Momentum of the car = P = 10,000.00 kgm/s

$m=\frac{P}{v}$

$m=\frac{ 10,000.00 kgm/s}{15.0 m/s}=666.67 kg$

666.67 kg is the mass of a car.

meriva

The metal is sodium, Na.

Explanation:

K₂O is an ionic compound in which K is in the oxidation state of +1 and it belongs to group 1.

Group 1 elements also form oxides with the metals with the general formula M₂O and M being Na, K, Li and so on.

Metals Like sodium and Potassium are so brittle in nature and also their oxides.

So the other metal that form metal oxide which is brittle as well as ionic in nature, and so the metal oxide is Na₂O.

So the metal is sodium, Na.
