Answer:

Power = 1333.33[watts]

Explanation:

First we must find the weight of the mass that is lifting.

m = 100 [kg]

W = m * g

where:

g = gravity = 10 [m/s^2]

W = 100*10 = 1000 [N]

We know that work is defined as the product of force by distance.

work = W * d

work = 1000 * 2

work = 2000 [J]

And power is defined as work done at a given time.

Power = work / time

Power = 2000/1.5

Power = 1333.33[Watt]
