Most comets come from an area called the oort cloud true or false

True

Explanation:

Oort cloud is an icy region. It is named after a Dutch Astronomer who discovered it, theoretically. It is a spherical region that stretches far beyond Pluto, in our Solar system.

The region over which it stretches beyond the Sun is estimated to be about one and half light years and more. Temperatures are between 0 C to 4 C, in that region. Comets, ice chunks planetesimals are all a part of that region. These exist in  huge numbers.

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s
