Question

In raising an object vertically at a constant speed of 2 m / s 10 watts of power is developed the weight of the object is

Answer 1

Answer:

5N

Explanation:

Power = Workdone/Time

Since workdone = Force * distance = mgh

Power = mgh/t

Given

Power = 10watts

speed = 2m/s

Power = Weight * velocity

Substitute

10 = Weight * 2

Weight = 10/2

Weight = 5N

Hence the weight of the object is 5N
