mass of the object=1000kg
time taken=1 min(60sec)
height attained =10 m
velocity attained= 10 m/s
∴ kinetic energy in the body 
E= 1/mv^2
E=1/2*1000*10^2
E=500*100
E=50000 J
∴power=energy/time
P=50000/60
P=833.3 W
∵ 1 W= 746 H.P
∴833.3W=746**833.3
              =621641.8
the answer is 62164.8 W or 62.1648 kW.
          i hope that this will help u..............^_^

Mass=1000kg
time taken=1 minute=60 second
distance=10m
velocity=1/2×mass×velocity×velocity
=1/2×1000×10×10
=500×10×10
=50000watts
in horse power=watts×0.00134
=50000×0.00134
=50000×134/100000
=5×134/10
=134/2
=62 horse power
