Answer:

(1)


v_1=-v_2

(2)


v_i=√(v_f^2-2ad)

(3)


v=√(a_cr)

(4)


r=\sqrt{G(m_1m_2)/(F_g)}

(5)


v_{i_(,2)}= \frac{(m_1+m_2)v_f-m_1v_{i_(,1)}}{m_2} }

Step-by-step explanation:

We are given a set of basic physic formulas. We are asked to solve these given literal equations for a certain variable.

What are literal equations?

Literal equations are equations that involve multiple variables, where you're typically solving for one variable in terms of the others. In other words, you manipulate the equation to isolate a specific variable on one side of the equation while the other variables are on the other side.


\hrulefill
Question #1:
v_1 + v_2=0; solve for 'v₁'

Subtract 'v₂' from either side of the equation:


\therefore \boxed{\boxed{v_1=-v_2}}

Question #2:
v_f^2=v_i^2 + 2ad; solve for 'v_i'

Subtract '2ad' from either side of the equation:


\Longrightarrow v_i^2=v_f^2-2ad

Take the square root of both sides of the equation:


\therefore \boxed{\boxed{v_i=√(v_f^2-2ad)}}

Question #3:
a_c=(v^2)/(r); solve for 'v'

Multiply each side of the equation by 'r':


\Longrightarrow v^2=a_cr

Take the square root of both sides of the equation:


\therefore \boxed{\boxed{v=√(a_cr) }}

Question #4:
F_g=G(m_1m_2)/(r^2); solve for 'r'

Multiply each side of the equation by 'r²':


\Longrightarrow F_gr^2=Gm_1m_2

Divide each side of the equation by 'F_g':


\Longrightarrow r^2=G(m_1m_2)/(F_g)

Take the square root of both sides of the equation:


\therefore \boxed{\boxed{ r=\sqrt{G(m_1m_2)/(F_g)} }}

Question #5:
m_1v_{i_(,1)}+m_2v_{i_(,2)}= (m_1+m_2)v_f; solve for 'v_{i,2}'

Subtract 'm₁v_{i,1}' from either side of the equation:


\Longrightarrow m_2v_{i_(,2)}= (m_1+m_2)v_f-m_1v_{i_(,1)}

Divide each side of the equation by 'm₂':



\therefore \boxed{\boxed{v_{i_(,2)}= \frac{(m_1+m_2)v_f-m_1v_{i_(,1)}}{m_2} }}

Thus, all parts have been solved.
