How much power is required to lift a 30.0 N chair 0.20 m in 2.0 s?

To calculate the power required to lift the chair, we first find the work done, which is the product of force and distance. The work done is ( W = F \times d = 30.0 , \text{N} \times 0.20 , \text{m} = 6.0 , \text{J} ). Power is then calculated as work done over time, ( P = \frac{W}{t} = \frac{6.0 , \text{J}}{2.0 , \text{s}} = 3.0 , \text{W} ). Thus, the power required to lift the chair is 3.0 watts.
