Question :-

• A body accelerates from rest for 5 seconds with a uninform acceleration of 9.8 m/s. What would be the final velocity of the body?

$\text{\large\underline{\red{Answer:-}}}$

• Final velocity of the body is 49 m/s

$\text{\large\underline{\orange{Given:-}}}$

• Acceleration of the body (a) = 9.8 m/s²
• Time (t) = 5 seconds
• Initial velocity (u) = 0 m/s

$\text{\large\underline{\pink{To Find:-}}}$

• The final velocity (v) of the body?

$\text{\large\underline{\green{Explaination:-}}}$

• As we have the initial velocity, the time and the acceleration of the body, then the final velocity is given by,

• $\large { \underline{ \boxed{ \textsf{v = u + at }}}}$

Where,

• v is the final velocity
• u is the initial velocity
• a is the acceleration
• t is the time taken

As we have all the required values,let's substitute them

ㅤㅤㅤ$\begin{gathered} \large \tt \dashrightarrow{}v = 0 + 9.8 \times 5 \\ \\ \large \tt \orange{\dashrightarrow{}v = 49 \: ms}\end{gathered}$
