As we know Work is a form of energy so W=m×g×h= 200×2.5×10=5000J and Power=Work/time=5000/5= 1000W.
arpi240803:
but how will kgf turn to N(newton)?
you can also understand W= F.S=m.g.s here m=200 g=10 and s=2.5m simple.
no. ...i am telling that..... how did 200kgf turn to 200N??
Weight =m ×g so 200×9.8= m× 9.8 hence m=200
