Question

If a particle starting from rest is moving with a uniform accelaration of 10m/s, then the final velocity when it covers a distance of 2km is​

Answer 1

Explanation:

$Given \: it \: , u=0 (particle starts from rest),</p><p> \\ acceleration \: (a) = 10 \frac{m}{s} \\ distance \: (s) = 2000m \\ by \: the \: third \: equation \: of \: motion \: \\ {v}^{2} = {u}^{2} + 2as \\ {v}^{2} = 2 \times 10 \times 2000 \: \frac{m}{s} \\ {v}^{2} = 40000 \frac{m}{s} \\ v = 200 \frac{m}{s} \\ hope \: it \: will \: help \: you..$
