Question

1. Given that u² =-2as (In units), using this equation find final velocity.
2. Given that S = 2t- 1/2 3t²(In SI units), using this equation find the acceleration

Answer 1

Explanation:

1) solution:-

$1){v}^{2} = {u}^{2} + 2as \\ {v}^{2} = - 2as + 2as \\ v = 0 \\ 2)v = \frac{ds}{dt} \\ v = 2 - 3t \\ by \: differentiating \: velocity \: we \: will \: get \: acceleration \\ a = - 3$
