Question

If initial velocity of an object 10m/s and final velocity of that object 20m/s if time taken in change of velocity is 10s then find acceleration?​

Answer 1

$\sf{\large{\underline{\underline{EXPLANATION}}}}$

$\sf{Given}\begin{cases}\sf{u=10ms^{-1}}\\ \sf{v=20ms^{-1}}\\ \sf{t=10s}\\ \sf{a=??}\end{cases}$

$\textbf{\underline{Using equation of motion,,}}</p><p>$

$\mathtt{\boxed{\blue{v=u+at}}}$

$\sf{\implies{20=10+10a}}$

$\sf{\implies{\frac{20-10}{10}=a}}$

$\sf{\implies{\cancel\dfrac{10}{10}=a}}$

$\sf{\implies{a=1ms^{-2}}}$

Therefore,,

$\sf{\boxed{a=1ms^{-2}}}$

Answer 2

$\huge{\underline{\underline{\sf{✩Required \:Answer✩}}}}$

✩Given:-

. Initial velocity = 10m/s

. final velocity = 20m/s

. Time taken in change of velocity = 10s

✩ To finD :-

. Acceleration of object

$\huge {\underline{\bf {\red{[✩Formula\: used✩]}}}}$

$\: a \: = \frac{v - u}{t}$

here,

a = acceleration, v = final velocity, u = initial velocity, t = time taken

✩ Explanation :-

Using formula of acceleration (given above)

$a \: = \frac{20 - 10}{10} \\ \\ = > a = \frac{10}{10} \\ \\ = > a \: = 1m/s²$

Hence,

Acceleration of object= 1m/s²
