Two billiard balls move toward each other on a table. the mass of the number three ball, m1, is 5 g with a velocity of 3 m/s. the mass of the eight ball, m2, is 6 g with a velocity of 1 m/s. after the balls collide, they bounce off each other. the number three ball moves off with a velocity of 5 m/s. what is the final velocity and direction of the eight ball?

+5.7 m/s

Explanation: I had the same question for physics.

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 .

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2
