What is the change in momentum of a car weighing 1500kg when its speed increases from 36km h to 72km h uniformly?

Sagot :

The change in momentum of the car is 15000 kg m/s.

Momentum is the strength gained by a moving body. It is calculated as the product of mass and velocity. Momentum is a vector quantity, which means it has both magnitude and direction.

We get the formula for calculating force from momentum from newton's second law. According to this law, " The force is equal to the time rate of change in momentum."

i.e., Force = Final momentum - initial momentum/ time

In the given question, we have to find a change in momentum

i.e. Force = Final momentum - initial momentum/ time

In the given question, we have to find change in momentum

Δp = [tex]M_{2[/tex][tex]V_{2[/tex] - [tex]M_{1[/tex][tex]V_{1[/tex]

      = M ( [tex]V_{2[/tex] - [tex]V_{1[/tex])\

      = 1500 (72-36) ×5/18

      = 1500×2×5

       = 15000 kg m/s
