An object with a velocity (v) of 9 m/s and a linear momentum (p) of 72 kg.m/s, has a mass (m) of 8 kg.
<h3>What is momentum?</h3>
In Newtonian mechanics, linear momentum, or simply momentum, is the product of the mass and velocity of an object.
It is a vector quantity, possessing a magnitude and a direction.
The mathematical expression for momentum is:
p = m . v
where,
- p is the linear momentum of the object.
- m is the mass of the object.
- v is the velocity of the object.
An object has a velocity (v) of 9 m/s and its linear momentum (p) is 72 kg.m/s. We will use the definition of linear momentum to calculate the mass of the object.
p = m . v
m = p / v
m = (72 kg.m/s) / (9 m/s) = 8 kg
An object with a velocity (v) of 9 m/s and a linear momentum (p) of 72 kg.m/s, has a mass (m) of 8 kg.

1 Newton of force is required to produce that.....
Answer:
Sink
Explanation:
The normal density of water is 1 g/cm3. Since the rock has a higher density of 1.72g/cm3, it will sink in water.
Answer:
178.4 times
Explanation:
We have Newton formula for attraction force between 2 objects with mass and a distance between them:
where 
is the gravitational constant on Earth. 
is the masses of the 2 objects. and R is the distance between them.
From here we can calculate the ratio of gravitational force between the moon and the sun
We can divide the top and bottom by G and M
So the gravitational force of the sun is about 178 times greater than that of the moon to an object on Earth
