1sec∗=5seconds
1kg∗=20kg
1m∗=10m
1watt∗=1kgm2sec−3
=120kg∗(110m∗)2(15sec∗)−3
=120×1100×125kg∗m∗2sec∗−3
=116watt∗
Hence 1 unit of power=116watts
Hence b is the correct answer.

F=m.a
and you know that unit of force is Newton.
if force =1N then a=1/2
hence 1N represents 1/2 force
and you know that unit of force is Newton.
if force =1N then a=1/2
hence 1N represents 1/2 force
