the above problem can be solved as
horizontal distance to be travelled is 100 - 92= 8m
vertical distance to be travelled = 16m
let be the horizontal velocity =constant here
now vertical sistance equation is =ut+ g
where u is vertical initial velocity
t is time taken to travel 8m i.e., reaching time to land second hill
as vertical initial velocity is 0
so above equation can be written as for time t,
t=
so t= sec.
so t = 1.277 sec.
now taking horizontal distance as = X t
16=
on solving above we get minimum horizontal velocity required to land on second hill as = 12.52 m/sec
