Answer:
Here you go bro.......
Explanation:
power = work / time
work = force x displacement
so power = force x displacement / time, where time is in sec, force is in N
displacement = 10m
time = 1min = 60s
power = 2KW = 2000W {1KW =1000W}
power = force x displacement / time
2000 = force x 10 /60
2000 = force x 1/6
force = 12000N
force = weight of the body = mg
12000 = mg {g = 9.8m/s²}
12000 = 9.8m
m = 12000/9.8
m = 1224.5kg
