How much power is required to lift a 2.0 kg mass at a speed of 2.0 m/s? a. 2.0 w c. 9.8 w b. 4.0 w d. 39 w

The power required to lift a 2 kg mass at a speed of 2 m/s is 39 W.

Option D

Explanation:

Power required to lift a mass of about 2 kg will be equal to work done attained by the object per unit time. And, the mass (m) of the object is given as 2 kg and speed (v) as 2 m/s, then

And, we know the following formula,

By applying this into the power equation, we get,

Hence, the power required to lift a mass, the rounded value would be 39 W.
