simple...

initial velo=u

accel=a

using s=ut+.5at^2

150=2t+2a ......... u+a=75

for second case total s=150+210=360    time =4+2=6

360=6u+18a

solve these eq to find u and a

hence find velo after 9secs....

easy...find five AMs and HMs bet 97 and 99

the am of these inserted terms will be the fourth term of the ap series (i.e 98 )starting from 97

similarly for harmonic series in which the hm of inserted terms is 97.9
