easy

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.........$metres$

A

$36$

B

$40$

C

$100$

D

$0$

Solution

(a) Distance travelled in ${n^{th}}$ second $ = u + \frac{a}{2}(2n – 1)$

Distance travelled in ${5^{th}}$ second

$ = 0 + \frac{8}{2}\left( {2 \times 5 – 1} \right)$

$=36\,m$

A three-wheeler starts from rest, accelerates uniformly with $1\; m/s^{2}$ on a straight road for $10\; s$, and then moves with uniform velocity. Plot the distance covered by the vehicle during the $n ^{\text {th }}$ second $( n =1,2,3 \ldots .)$ versus $n$. What do you expect this plot to be during accelerated motion : a straight line or a parabola?
