Question

( S_{2 n}=u+frac{1}{2} a(2 n-1) )
Hese, ( n=3 )
( S_{3 k d}=frac{5 a}{2}, S_{4 m}=frac{7}{2} a )
1. muctuse in displacement is ( =frac{S_{4}left(hbar-S_{X} Aright.}{A S_{X} A} times 100 )
( =frac{0}{5 a} times 100=40^{circ} )

# 29. A particle moves with constant acceleration along a straight line starting from rest. The percentage increase in its displacement during the 4th second compared to that in 3rd second is
