Hi friend,
-----------------------------------------------------
h= 15m, t= 15 s ,m= 10kg, g=10m/s2
p=w/t = f .S /t = m.a.s /t = m.g.s /t
= 10.10.15/15
=1500/15
=100watts

Answer: given H=15m,T=15s,m=10kg
So,
Workdone=mgh(it is against gravity)
W=10×10×15=1500 joules
So,
Power =work÷time
P=1500÷15=100 joules.
