13 \(h = 3t^2\)
(a) Work out the value of \(h\) when \(t = 5\) (2)
\(h = 3t^2\)
(b) Work out the value of \(t\) when \(h = 108\) (2)
(c) Make \(a\) the subject of the formula \[v = u + at\] (2)

|---|---|---|---|
| \(108 = 3t^2\) \(t^2 = \tfrac{108}{3} = 36\) | \(\pm 6\) | 2 | M1 for \((t^2 =) \dfrac{108}{3}\) (= 36) A1 for 6 or \(-6\) or both |
| Answer | Mark | Notes |
|---|---|---|
| \(a = \dfrac{v - u}{t}\) | 2 | M1 for subtracting \(u\) from both sides or dividing both sides by \(t\) as a first step A1 for \(a = \dfrac{v - u}{t}\) oe |
