Question

A body started from rest attain a velocity of 30 m/s in 2s .find its acceleration

Answer 1

$\blue{\bold{\underline{\underline{Answer:}}}}$

$\green{\therefore{\text{Acceleration=15\:m/}s^{2}}}$

$\orange{\bold{\underline{\underline{Step-by-step\:explanation:}}}}$

• In the given question information given about a body if it starts from rest and attains the velocity 30 m/sin 2 seconds.

• We have to find acceleration of body.

$\green{\underline\bold{Given :}} \\ :\implies \text{Initial\:velocity(u)=0 m/s} \\ \\ :\implies \text{Final \: velocity (v)= 30 \:m/s} \\ \\ :\implies \text{Time = 2 \: sec} \\ \\ \red{\underline \bold{To \: Find : }} \\ :\implies \text{Acceleration= ?}$

• According to given question :

$\bold{Using \: first \: equation \: of \: motion : } \\ : \implies v = u + at \\ \\ : \implies 30= 0 + a \times 2 \\ \\ : \implies 10 \times a = {30} \\ \\ : \implies a = \frac{30}{2} \\ \\ \green{ : \implies \text{a = 15 \: m}/{s}^{2} }$
