Question

A particle is having uniform acceleration. If its displacement from t to $(t + 1)$ second is $120$ $m$ and change in velocity is $50 \;m/s$. Find its displacement (in m) in $(t + 2)^{th}$ second

Answer 1

$\text{Displacement will be:}$

$a=50\;m/s^2$

$120=u+\frac{a}{2}(2(t+1)-1)$

$u=120-25(2t+1)$

$s'=u+\frac{a}{2}(2(t+2)-1)$

$=u+25(2t+3)$

The Correct Answer is : $170$
