Question

An object undergoes an acceleration of 8/sec starting from rest. Find the distance travelled in 1 second.

Answer 1

The distance travelled in 1 sec is equal to 8

Answer 2

Aɴꜱᴡᴇʀ :-

• Distance travelled by the motor boat is 4m

_________________

Gɪᴠᴇɴ :-

✭ Acceleration (a) = 8 m/s²

✭ Initial velocity (u) = 0 m/s

✭ Time (t) = 1 seconds

Tᴏ ꜰɪɴᴅ :-

➤ The distance (s) travelled during this time?

❍ We can find out answer here with the help of the second law of motion, that is,

$\large{\underline{ \boxed{ \green{ \sf{}s = ut + \frac{1}{2}a {t}^{2} }}}}$

Substituting the given values,

$\begin{gathered}\large \tt \leadsto{}s = 0 \times 1+ \frac{1}{ \cancel2} \times \cancel8 \times 1\times 1\\ \\ \tt \large \leadsto{}s = 4\times 1 \times 1 \\ \\ \large \tt \pink{\leadsto{}s = 4 \: \sf{}m}\end{gathered}$
