If the momentum of a car is reduced by half, assuming mass did not change, what must also have been reduced by half?

Velocity is halved

Explanation:

Momentum is contingent on mass and velocity. The quantity of motion in a body is called the momentum of the body.

  Momentum  = mass x velocity

Now, if mass does not change and momentum is reduced by half, it suggests that the velocity was reduced by half.

Velocity is directly related to momentum.

i think its 100

i hope this !

it is reliable if two scientists recorded it
