Vedclass · Answer

Using the equation of motion $s=u t+\frac{1}{2} a t^{2}$

Distance travelled in $5\, s$ $s=u 	imes 5+\frac{1}{2} a 	imes 5^{2}$

Or       $ s=5 u+\frac{25}{2} a$ ........... $(i)$

Similarly, distance travelled in $4 \,s$ ,  $s^{\prime}=4 u+\frac{16}{2} a$ ............ $(i i)$

Distance travelled in the interval between $4^{	ext {th }}$ and $5^{	ext {th }}$ second $=\left(s-s^{\prime}ight)=\left(u+\frac{9}{2} aight)\, m$

Obtain a relation for the distance travelled by an object moving with a uniform acceleration in the interval between $4^{th}$ and $5^{th}$ seconds.
