Question

Rearrange the equation below with the required unknown becoming the subject

a. V as subject
b. U as subject
c. a as subject
d. S as subject

Answer 1

a.

`{v}^(2) = {u}^(2) + 2as \\ v = \sqrt{ {u}^(2) + 2as}`

b.

`{v}^(2) = {u}^(2) + 2as \\ {u}^(2) = {v}^(2) - 2as \\ u = \sqrt{ {v}^(2) - 2as}`

c.

`{v}^(2) = {u}^(2) + 2as \\ 2as = {v}^(2) - {u}^(2) \\ a = \frac{ {v}^(2) - {u}^(2) }{2s} \\ \\ a = \frac{ {v}^(2) }{2s} - \frac{ {u}^(2) }{2s}`

d.

`{v}^(2) = {u}^(2) + 2as \\ 2as = {v}^(2) - {u}^(2) \\ s= \frac{ {v}^(2) - {u}^(2) }{2a} \\ \\ s = \frac{ {v}^(2) }{2a} - \frac{ {u}^(2) }{2a}`
