Momentum

[tex]\large\mathbb{ \red{PROBLEM} }{:}[/tex]

A car of mass 1000 kg is moving with a velocity of 20 m/s. Calculate its momentum.

[tex]\large\mathbb{ ANSWER }{:}[/tex]

  • 20,000 kg • m/s

[tex]\large\mathbb{ \green{EXPLANATION }}{:}[/tex]

To find its momentum, we multiply the given mass and velocity of car.

======================================

[tex]\large\mathbb{ \blue{GIVEN} }{:}[/tex]

  • m = 1000 kg
  • v = 20 m/s
  • p = ?

Where m is a mass, v is a velocity and p is a momentum

[tex]\large\mathbb{ \red{FORMULA} }{:}[/tex]

  • [tex]\large \boxed{ \sf p = mv}[/tex]
  • [tex] \sf momentum \: = \: mass \times velocity[/tex]

[tex]\large\mathbb{ \green{SOLUTION} }{:}[/tex]

Let's substitute the all given in a our formula:

  • [tex]\large { \sf p = mv}[/tex]
  • [tex]\large { \sf p = (1000kg)(20m/s)}[/tex]
  • [tex] \sf p \: = \: 20,000 \: \red{kg} \: • \: \blue{m/s}[/tex]
  • [tex] \boxed{\sf p \: = \: 20,000 \: \red{kg} \: • \: \blue{m/s}}[/tex]

∴ The momentum of a car is 20,000 kg • m/s
