A car with two people traveling down the road has a mass of 100 kg and a velocity of 5 m/s. The car pulls over and picks up two
Oliga [24]

Answer:

750 kg.m/s

Explanation:

Momentum is the product of mass and velocity in kg.m/s.

In this case, initial momentum⇒p=m × v where m is mass and v is velocity

initial mass of car m₁=100 kg

Initial velocity of car v₁=5 m/s

Initial momentum= 100×5= 500 kg.m/s

New mass after picking two extra people m₂= 150 kg

Velocity  stays the same v₂=v₁= 5 m/s

New momentum= m₂× v₂

p=150×5=750 kg.m/s
