Answer 1

Answer:

The product of acceleration and displacement

$from \: the \: equations \: of \: motion \\ as = \frac{ {v}^{2} - {u}^{2} }{2} \\ \\ from \: the \: graph \: a \: \times s \: is \\ 10 \times 2 + \frac{1}{2} \times 10 \times 2 - \frac{1}{2} \times 10 \times 2 \\ = 20 {m}^{2} {s}^{ - 2} \\ u = 0 \\ \frac{ {v}^{2} }{2} = 20 \\ velocity \: after \: x = 6 \: is \\ v = 2 \sqrt{10} m {s}^{ - 1}$
