Please at least help me cause I have no idea

Answer 1

Answer:

Solving the given formula for v2 gives us:

$a(t_2-t_1)+v_1 = v_2$

Step-by-step explanation:

Solving an equation for a particular variable means that the variable has to be isolated on one side of the equation.

Given equation is:

$a = \frac{v_2-v_1}{t_2-t_1}$

Multiplying both sides by t2-t1

$(t_2-t_1) . a = \frac{v_2-v_1}{t_2-t_1} . (t_2-t_1)\\a(t_2-t_1) = v_2-v_1$

Adding v1 to both sides of the equation

$a(t_2-t_1)+v_1 = v_2-v_1+v_1\\a(t_2-t_1)+v_1 = v_2$

Hence,

Solving the given formula for v2 gives us:

$a(t_2-t_1)+v_1 = v_2$
