MCQ
If body having initial velocity zero is moving with uniform acceleration $8 m / sec ^2$ the distance travelled by it in fifth second will be
  • 36 metres
  • B
    40 metres
  • C
    100 metres
  • D
    Zero

Answer

Correct option: A.
36 metres
(a) Distance travelled in $n^{\text {th }}$ second $=u+\frac{a}{2}(2 n-1)$Distance travelled in $5^{\text {th }}$ second $=0+\frac{8}{2}(2 \times 5-1)=36 \mathrm{~m}$
