A biker with a mass of 75 kg moves along the path with a constant velocity of 5 m/s
What is the biker's momentum?


Sagot :

Answer:

[tex]375\ \text{kg m/s}[/tex]

Explanation:

[tex]m[/tex] = Mass of biker = [tex]75\ \text{kg}[/tex]

[tex]v[/tex] = Velocity of bike = [tex]5\ \text{m/s}[/tex]

Momentum is given by the product of mass and velocity so,

[tex]p=mv[/tex]

[tex]\Rightarrow p=75\times 5[/tex]

[tex]\Rightarrow p=375\ \text{kg m/s}[/tex]

The momentum of the biker is [tex]375\ \text{kg m/s}[/tex].

The biker's momentum will be "375 kg m/s".

Momentum and Velocity

The proportion or resultant of a subatomic particle mass as well as the speed. Momentum would be a vector quantity, which means it does have a magnitude and therefore an orientation or directions.

According to the question,

Biker's mass, m = 75 kg

Biker's velocity, v = 5 m/s

We know the relation,

Momentum = Mass × Velocity

or,

→ p = mv

By substituting the values, we get

      = 75 × 5

      = 375 kg m/s

Thus the above answer is correct.
