first calculate work :
=F × D
=(m × a) × D
=6.1225 × 9.8 × 10
=600.005 J
then divide it by time taken :
=600.005 ÷ 5
=120.001 W ans.

here,
F=
srry about that......
F = force, D= displacement, m= mass, a= acceleration.
to calcute mass - Weight = mass * gravitational constant , 60 = mass * 9.8m/s2 , mass = 6.1225

work done=m×g×h
m=60kg
h=10m
g=9.8m/s²
w=60×10×9.8=5880
power=w÷t
5880÷5=1176W
m=60kg
h=10m
g=9.8m/s²
w=60×10×9.8=5880
