(a) Rearrange this formula to make \(d\) the subject.\[f = 5d + 4\] [2]
(b) Use the formula\[v = u + at\]
to find the final velocity, when
- the initial velocity is 5 m/s
- the acceleration is 7.5 m/s²
- the time is 6 seconds.
.................... m/s [2]

|---|---|---|---|
| \(d = \dfrac{f - 4}{5}\) or \(d = \dfrac{f}{5} - \dfrac{4}{5}\) | 2 | M1 for \(f - 4 = 5d\) or \(\dfrac{f}{5} = d + \dfrac{4}{5}\) or \(\dfrac{f - 4}{5}\) or \(\dfrac{f}{5} - \dfrac{4}{5}\) as answer | |
