P = F.V = (1000 + 10000)0.5 = (11000/2) = 5500 = 5.5 kW

Q. $1000 N$ force is required to lift a hook and $10000 N$ force is required to lift a load slowly. Find power required to lift hook with load with speed $v = 0.5 m / sec$ .

5 kW

5.5 kW

1.5 kW

4.5 kW

P = F.V = (1000 + 10000)0.5
$= \frac{11000}{2}$ = 5500 = 5.5 kW
