Answer:
Meteoroids
Explanation:
Meteoroids are small masses of rocks or metallic bodies that often found to orbit around the Sun. The size of a meteoroid is smaller in comparison to the asteroids. The elements that are found in the meteoroids are extraterrestrial nickel and iron. Meteoroids are often formed by the fragments from bodies present in universe such as Mars or Moon and thrown into space by an impact. After formation they often come in the range of attraction of Sun and start orbiting around it.
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
