Question

How much power is required to lift a 2.0kg mass at a speed of 2.0m/s

Answer 1

39 J

P=Fd/t i belive is the answer

Answer 2

Power, P = 39.2 watts

Step-by-step explanation:

Given that,

Mass of an object, m = 2 kg

Speed of the object, v = 2 m/s

To find,

Power required to lift the object

Solution,

The work done divided by time taken is called power required to lift an object. Its expression is given by :

`P=(W)/(t)`

Since, W = F.d

`P=(F.d)/(t)`

And v = d/t

`P=F* v`

`P=m* g* v`

`P=2\ kg* 9.8\ m/s^2* 2\ m/s`

P = 39.2 watts

So, the power required to lift an object is 39.2 watts.
