Question

18. A body starts from rest travels a certain distance in time t with constant acceleration. How much
time will it take to travel last 1/4th distance in terms of t.

Answer 1

Answer:

From the question a  graph is drawn above,

Area of v−t graph⟹ distance travelled

vavg=t1+t2+t38s

21vm×t1=s

t1=vm2s

t2×vm=2s

t2=vm2s

21×t3×vm=5s

t3=vm10s

vavg=vm2s+vm2s+
