What is the velocity of a 24 kg object with 108 kg m/s of momentum? A) 3 m/s
B) 4.5 m/s
C) 6 m/s
D) 84 m/s

The velocity of the object is 4.5 m/s

Explanation:

Momentum is equal to mass times velocity.  We can rearrange that relationship to say that velocity is equal to momentum divided by mass.  With that we can say:

v = 108 kg m/s / 24kg

v = (108 / 24) m/s

v = 4.5 m/s

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .

the answer is a 3.8cm

explanation:
