Question

A body of mass 1kg is made to travel
with a uniform acceleration of 30 cm/s2
over a distance of 2m, then work to be
done is​

Answer 1

Answer:

$2as = {v}^{2} - {v}^{2} \\ {v}^{2} - {u}^{2} = 2 \times 3 \times {10}^{ - 2} \times 2 \\ = 1.2 \\ w \: d = triangle(ke) \\ = \frac{1}{2} m( {v}^{2} - {u}^{2} ) \\ = \frac{1}{2} \times 1 \times (1.2) \\ =0.6J</p><p></p><p>$
