Question

Use the formula for delectation d= (Vf-Vi)/t. f is the final velocity , i is the initial velocity and t is time . Solve for I

Answer 1

Answer:

A = (vf - vi) / t    <== call this the "given  equation "=====================================

For t :Multiply each side of the given equation by 't' :    A t = (vf - vi)Divide each side by 'A' :                                        t = (vf - vi) / A=====================================

For vi :Multiply each side of the given equation by 't' :    A t = (vf - vi)Subtract ' vf ' from each side:                             A t - vf = -viMultiply each side by  -1 :                                  vf - A t = vi=====================================

For vf :Multiply each side of the given equation by 't' :    A t = (vf - vi)Add ' vi ' to each side:                                      A t + vi = vf

Hope it's correct :)
