QUESTION
Q1) A body starts from rest and travels 120cm in the 8th second, then acceleration of the body is .. [AFMC1997]



SOLUTION

According to formula for displacement in nth second
dispacement in n the second
Here Sn=120cm=1.2m
time n=8 sec
initial velocity u=0 ( given)
Substitute above values in equation and solve for 'a' we get
a=0.16m /s2
Answer=(d)
