Billiard ball a of mass ma = 0.125 kg moving with speed va = 2.80 m/s strikes ball b, initially at rest, of mass mb = 0.140 kg . as a result of the collision, ball a is deflected off at an angle of θ′a = 30.0∘ with a speed v′a = 2.10 m/s, and ball b moves with a speed v′b at an angle of θ′b to original direction of motion of ball a. part csolve these equations for the angle, θ′b, of ball b after the collision. do not assume the collision is elastic. express your answer to three significant figures and include the appropriate unitspart dsolve these equations for the speed, v′b, of ball b after the collision. do not assume the collision is elastic. express your answer to three significant figures and include the appropriate units

Explanation:

Law Newton's conservation motion

Axis x

Axis y

So the velocity

The angle can be find using both velocity factors

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.

reserve is the answer
