A 20 kg cart moving at 4 m/s has how much momentum?

40 kg*m/s
40 kg*m/s

5 kg*m/s
5 kg*m/s

80 kg*m/s

Respuesta :

Answer:

We conclude that the required momentum is 80 kgm/s.

Explanation:

Given

  • Mass m = 20 kg
  • Velocity v = 4 m/s

To determine

The momentum p = ?

Important Tip:

  • The momentum of an object is the product of mass and velocity.

We can determine the momentum using the formula

[tex]p = mv[/tex]

where

  • p is the momentum
  • m is the mass
  • v is the velocity

now substituting m = 20 and v = 4 using the equation

[tex]p = mv[/tex]

[tex]p = (20) (4)[/tex]

[tex]p = 80[/tex] kg m/s

Therefore, we conclude that the required momentum is 80 kgm/s.

The momentum of the moving cart is 80kgm/s.

HOW TO CALCULATE MOMENTUM:

  • The momentum of a body can be calculated by multiplying the mass of that body by its velocity. That is;

Momentum (p) = mass (m) × velocity (v)

  • According to this question, a 20kg cart moving at 4 m/s will have a momentum as follows:

Momentum (p) = 20kg × 4m/s

Momentum (p) = 80kg*m/s.

  • Therefore, the momentum of the moving cart is 80kgm/s.
