# A particle moves in a straight line under constant acceleration of 4m/s^2. If its velocity at t=0 is 10m/s, the displacement of the particle in the 5th second of its motion isplz also show the procedure of doing the problem also.

$\\ a=4 m/s^2 \\ at t=0, u=10 m /s \\ displacement in 5 th sec$

$S_{n}=u+\frac{1}{2}(2 n-1) a\Rightarrow S_5=10+\frac{1}{2}((2\times 5)-1)\times 4=28 m$
