Answer:
using equation of motion :s=ut+
2
at
2
distance traveled in first second:
h
1
=45m
t
a
=
g
u
,where t
a
is time of ascent
t
a
=5s
so at t=2s last 3 sec of upward motion starts
height at t=2s is :
h=50×2−
2
10×4
h=80m
H
max
=
2g
u

Hmax=125m
distance traveled in last 3 sec h
2
=H−h
h
2
=125−80
h
2
=45m
therefore h
1
=h
